This reverts commit 5f05285df691b1e82108eead7165feae238c95ef.
This commit assumes that every HID descriptor for ALS sensor has
presence of usage id ID HID_USAGE_SENSOR_LIGHT_COLOR_TEMPERATURE.
When the above usage id is absent, driver probe fails. This breaks
ALS sensor functionality on many platforms.
Till we have a good solution, revert this commit.

When accessing sq_tail_slot without protection from sq_lock, a race
condition can cause multiple SQEs to be copied to duplicate SQE slots. This
can lead to multiple stability issues. Fix this by moving the *dest
initialization in ufshcd_send_command() back under protection from the
sq_lock.

In commit 8930a6c20791 ("scsi: core: add support for request batching") the
block layer bd->last flag was mapped to SCMD_LAST and used as an indicator
to send the batch for the drivers that implement this feature. However, the
error handling code was not updated accordingly.
scsi_send_eh_cmnd() is used to send error handling commands and request
sense. The problem is that request sense comes as a single command that
gets into the batch queue and times out. As a result the device goes
offline after several failed resets. This was observed on virtio_scsi
during a device resize operation.
[ 496.316946] sd 0:0:4:0: [sdd] tag#117 scsi_eh_0: requesting sense

[ 506.787981] sd 0:0:4:0: [sdd] tag#117 abort
To fix this always set SCMD_LAST flag in scsi_send_eh_cmnd() and
scsi_reset_ioctl().

Since it's a divide-by-0 error, by tracking the code for potential

so let's guard against the possibility and log in the kernel if the
condition happens. This is specially useful since some data that
fills some denominators are read from the joycon HW in some cases,
increasing the potential for flaws.

__bio_for_each_segment assumes that the first struct bio_vec argument
doesn't change - it calls "bio_advance_iter_single((bio), &(iter),
(bvl).bv_len)" to advance the iterator. Unfortunately, the dm-integrity
code changes the bio_vec with "bv.bv_len -= pos". When this code path
is taken, the iterator would be out of sync and dm-integrity would
report errors. This happens if the machine is out of memory and
"kmalloc" fails.
Fix this bug by making a copy of "bv" and changing the copy instead.

in order to make sure event_work is done, __md_stop() will flush
workqueue with reconfig_mutex grabbed, hence if sync_work is still
pending, deadlock will be triggered.
Fortunately, former pacthes to fix stopping sync_thread already make sure
all sync_work is done already, hence such deadlock is not possible
anymore. However, in order not to cause confusions for people by this
implicit dependency, delay flushing event_work to dm-raid where
'reconfig_mutex' is not held, and add some comments to emphasize that
the workqueue can't be flushed with 'reconfig_mutex'.

Previously, the ice driver had support for using a handler for bonding
netdev events to ensure that conflicting features were not allowed to be
activated at the same time. While this was still in place, additional
support was added to specifically support SRIOV and LAG together. These
both utilized the netdev event handler, but the SRIOV and LAG feature was
behind a capabilities feature check to make sure the current NVM has
support.
The exclusion part of the event handler should be removed since there are
users who have custom made solutions that depend on the non-exclusion of
features.
Wrap the creation/registration and cleanup of the event handler and
associated structs in the probe flow with a feature check so that the
only systems that support the full implementation of LAG features will
initialize support. This will leave other systems unhindered with
functionality as it existed before any LAG code was added.

When creating new VSIs, they are assigned into an aggregator node in the
scheduler tree. Information about which aggregator node a VSI is assigned
into is maintained by the vsi->agg_node structure. In ice_vsi_decfg(), this
information is being destroyed, by overwriting the valid flag and the
agg_id field to zero.
For VF VSIs, this breaks the aggregator node configuration replay, which
depends on this information. This results in VFs being inserted into the
default aggregator node. The resulting configuration will have unexpected
Tx bandwidth sharing behavior.
This was broken by commit 6624e780a577 ("ice: split ice_vsi_setup into
smaller functions"), which added the block to reset the agg_node data.
The vsi->agg_node structure is not managed by the scheduler code, but is
instead a wrapper around an aggregator node ID that is tracked at the VSI
layer. Its been around for a long time, and its primary purpose was for
handling VFs. The SR-IOV VF reset flow does not make use of the standard VSI
rebuild/replay logic, and uses vsi->agg_node as part of its handling to
rebuild the aggregator node configuration.
The logic for aggregator nodes stretches back to early ice driver code from
commit b126bd6bcd67 ("ice: create scheduler aggregator node config and move
VSIs")
The logic in ice_vsi_decfg() which trashes the ice_agg_node data is clearly
wrong. It destroys information that is necessary for handling VF reset,. It
is also not the correct way to actually remove a VSI from an aggregator
node. For that, we need to implement logic in the scheduler code. Further,
non-VF VSIs properly replay their aggregator configuration using existing
scheduler replay logic.
To fix the VF replay logic, remove this broken aggregator node cleanup
logic. This is the simplest way to immediately fix this.
This ensures that VFs will have proper aggregate configuration after a
reset. This is especially important since VFs often perform resets as part
of their reconfiguration flows. Without fixing this, VFs will be placed in
the default aggregator node and Tx bandwidth will not be shared in the
expected and configured manner.

The pipe DMC seems to be making a mess of things in ADL. Various weird
symptoms have been observed such as missing vblank irqs, typicalle
happening when using multiple displays.
Keep all pipe DMC event handlers disabled until needed (which is never
atm). This is also what Windows does on ADL+.
We can also drop DG2 from disable_all_flip_queue_events() since
on DG2 the pipe DMC is the one that handles the flip queue events.

Since dsc_get_config now uses bigjoiner flags/pipes to compute DSC PPS

So call get bigjoiner config before calling dsc get config function.

The Laptop 13 (AMD Ryzen 7040Series) BIOS 03.03 has a workaround
included in the EC firmware that will cause the EC to emit a "spurious"
keypress during the resume from s0i3 [1].
This series of keypress events can be observed in the kernel log on
resume.
```
atkbd serio0: Unknown key pressed (translated set 2, code 0x6b on isa0060/serio0).
atkbd serio0: Use 'setkeycodes 6b <keycode>' to make it known.
atkbd serio0: Unknown key released (translated set 2, code 0x6b on isa0060/serio0).
atkbd serio0: Use 'setkeycodes 6b <keycode>' to make it known.
```
In some user flows this is harmless, but if a user has specifically
suspended the laptop and then closed the lid it will cause the laptop
to wakeup. The laptop wakes up because the ACPI SCI triggers when
the lid is closed and when the kernel sees that IRQ1 is "also" active.
The kernel can't distinguish from a real keyboard keypress and wakes the
system.
Add the model into the list of quirks to disable keyboard wakeup source.
This is intentionally only matching the production BIOS version in hopes
that a newer EC firmware included in a newer BIOS can avoid this behavior.

Pull CXL (Compute Express Link) fixes from Dan Williams:
"A collection of CXL fixes.
The touch outside of drivers/cxl/ is for a helper that allocates
physical address space. Device hotplug tests showed that the driver
failed to utilize (skipped over) valid capacity when allocating a new
memory region. Outside of that, new tests uncovered a small crop of
lockdep reports.
There is also some miscellaneous error path and leak fixups that are
not urgent, but useful to cleanup now.
- Fix alloc_free_mem_region()'s scan for address space, prevent false
negative out-of-space events
- Fix sleeping lock acquisition from CXL trace event (atomic context)
- Fix put_device() like for the new CXL PMU driver
- Fix wrong pointer freed on error path
- Fixup several lockdep reports (missing lock hold) from new
assertion in cxl_num_decoders_committed() and new tests"

Calling led_trigger_register() when attaching a PHY located on an SFP
module potentially (and practically) leads into a deadlock.
Fix this by not calling led_trigger_register() for PHYs localted on SFP
modules as such modules actually never got any LEDs.

This reverts commit 40613da52b13fb21c5566f10b287e0ca8c12c4e9 and the
subsequent fix to it:
cc22522fd55e ("PCI: acpiphp: Use pci_assign_unassigned_bridge_resources() only for non-root bus")
40613da52b13 fixed a problem where hot-adding a device with large BARs
failed if the bridge windows programmed by firmware were not large enough.
cc22522fd55e ("PCI: acpiphp: Use pci_assign_unassigned_bridge_resources()
only for non-root bus") fixed a problem with 40613da52b13: an ACPI hot-add
of a device on a PCI root bus (common in the virt world) or firmware
sending ACPI Bus Check to non-existent Root Ports (e.g., on Dell Inspiron
7352/0W6WV0) caused a NULL pointer dereference and suspend/resume hangs.
Unfortunately the combination of 40613da52b13 and cc22522fd55e caused other
problems:
- Fiona reported that hot-add of SCSI disks in QEMU virtual machine fails
sometimes.
- Dongli reported a similar problem with hot-add of SCSI disks.
- Jonathan reported a console freeze during boot on bare metal due to an
error in radeon GPU initialization.
Revert both patches to avoid adding these problems. This means we will
again see the problems with hot-adding devices with large BARs and the NULL
pointer dereferences and suspend/resume issues that 40613da52b13 and
cc22522fd55e were intended to fix.

Remove double-mapping of DMA buffers as it can prevent page pool entries
from being freed. Mapping is managed by page pool infrastructure and
was previously managed by the driver in __bnxt_alloc_rx_page before
allowing the page pool infrastructure to manage it.

Here "temp" is the number of characters that we have written and "size"
is the size of the buffer. The intent was clearly to say that if we have
written to the end of the buffer then stop.
However, for that to work the comparison should have been done on the
original "size" value instead of the "size -= temp" value. Not only
will that not trigger when we want to, but there is a small chance that
it will trigger incorrectly before we want it to and we break from the
loop slightly earlier than intended.
This code was recently changed from using snprintf() to scnprintf(). With
snprintf() we likely would have continued looping and passed a negative
size parameter to snprintf(). This would have triggered an annoying
WARN(). Now that we have converted to scnprintf() "size" will never
drop below 1 and there is no real need for this test. We could change
the condition to "if (temp <= 1) goto done;" but just deleting the test
is cleanest.

This flash drive reports write protect during the first mode sense.
In the past this was not an issue as the kernel called revalidate twice,
thus asking the device for its write protect status twice, with write
protect being disabled in the second mode sense.
However, since commit 1e029397d12f ("scsi: sd: Reorganize DIF/DIX code to
avoid calling revalidate twice") that is no longer the case, thus the
device shows up read only.
[490891.289495] sd 12:0:0:0: [sdl] Write Protect is on
[490891.289497] sd 12:0:0:0: [sdl] Mode Sense: 2b 00 80 08
This does not appear to be a timing issue, as enabling the usbcore quirk
USB_QUIRK_DELAY_INIT has no effect on write protect.

The reason is that although the device is detached, normal stop and
unbind operations are commanded from the driver. These operations are
not necessary in this situation, so avoid these logs when the device is
detached if the result of the operation is -ENODEV and if the new flag
informing about the disconnecting status is enabled.

This driver uses MMIO access for reading NVRAM from a flash device.
Underneath there is a flash controller that reads data and provides
mapping window.
Using MMIO interface affects controller configuration and may break real
controller driver. It was reported by multiple users of devices with
NVRAM stored on NAND.
Modify driver to read & cache NVRAM content during init and use that
copy to provide NVMEM data when requested. On NAND flashes due to their
alignment NVRAM partitions can be quite big (1 MiB and more) while
actual NVRAM content stays quite small (usually 16 to 32 KiB). To avoid
allocating so much memory check for actual data length.
