Allow all the RGMII modes to be used. This would allow us to represent
the hardware better in the device tree with RGMII_ID where in most

This reverts commit 42ec336f1f9d ("ALSA: hda: Disable regmap

Without regmap locking, there is a race between snd_hda_codec_amp_init()
and PM callbacks issuing regcache_sync(). This was caught by
following kernel warning trace:

Following the lifetime of the allocated 'roots' ulist, it gets freed
again in btrfs_qgroup_account_extent().
But this does not happen if the function is called with the
'BTRFS_FS_QUOTA_ENABLED' flag cleared, then btrfs_qgroup_account_extent()
does a short leave and directly returns.
Instead of directly returning we should jump to the 'out_free' in order to
free all resources as expected.

According to bd0e6c9614b9 ("usb: hub: try old enumeration scheme first
for high speed devices") the kernel will try the old enumeration scheme
first for high speed devices. This can happen when a high speed device
is plugged in.
But due to missing parentheses in the USE_NEW_SCHEME define, this logic
can get messed up and the incorrect result happens.

Currently when an error occurs when calling devm_gpiod_get_optional or
calling gpiod_to_irq it causes an uninitialized error return in variable
'error' to be returned. Fix this by ensuring the error variable is set
from da8xx_ohci->oc_gpio and oc_irq.
Thanks to Dan Carpenter for spotting the uninitialized error in the

When disconnected as USB B-device, suspend interrupt should come before
diconnect interrupt, because the DP/DM pins are shorter than the
VBUS/GND pins on the USB connectors. But we sometimes get a suspend
interrupt after disconnect interrupt. In that case we have devctl set to
99 with VBUS still valid and musb_pm_runtime_check_session() wrongly
thinks we have an active session. We have no other interrupts after
disconnect coming in this case at least with the omap2430 glue.
Let's fix the issue by checking the interrupt status again with
delayed work for the devctl 99 case. In the suspend after disconnect
case the devctl session bit has cleared by then and musb can idle.
For a typical USB B-device connect case we just continue with normal
interrupts.

btrfs_del_root_ref() will simply WARN_ON() if the ref doesn't match in
any way, and then continue to delete the reference. This shouldn't
happen, we have these values because there's more to the reference than
the original root and the sub root. If any of these checks fail, return
-ENOENT.

If we have the following sequence of events
btrfs sub create A
btrfs sub create A/B
btrfs sub snap A C
mkdir C/foo
mv A/B C/foo
rm -rf *
We will end up with a transaction abort.
The reason for this is because we create a root ref for B pointing to A.
When we create a snapshot of C we still have B in our tree, but because
the root ref points to A and not C we will make it appear to be empty.
The problem happens when we move B into C. This removes the root ref
for B pointing to A and adds a ref of B pointing to C. When we rmdir C
we'll see that we have a ref to our root and remove the root ref,
despite not actually matching our reference name.
Now btrfs_del_root_ref() allowing this to work is a bug as well, however
we know that this inode does not actually point to a root ref in the
first place, so we shouldn't be calling btrfs_del_root_ref() in the
first place and instead simply look up our dir index for this item and
do the rest of the removal.

btrfs_unlink_subvol takes the name of the dentry and the root objectid
based on what kind of inode this is, either a real subvolume link or a
empty one that we inherited as a snapshot. We need to fix how we unlink
in the case for BTRFS_EMPTY_SUBVOL_DIR_OBJECTID in the future, so rework
btrfs_unlink_subvol to just take the dentry and handle getting the right
objectid given the type of inode this is. There is no functional change
here, simply pushing the work into btrfs_unlink_subvol() proper.

There are few cases where the ndo_uninit() handler might be not
called if an error happens while device is initialized.
Since vlan_newlink() calls vlan_changelink() before
trying to register the netdevice, we need to make sure
vlan_dev_uninit() has been called at least once,
or we might leak allocated memory.

We currently punt any short read on a regular file to async context,
but this fails if the short read is due to running into EOF. This is
especially problematic since we only do the single prep for commands
now, as we don't reset kiocb->ki_pos. This can result in a 4k read on
a 1k file returning zero, as we detect the short read and then retry
from async context. At the time of retry, the position is now 1k, and
we end up reading nothing, and hence return 0.
Instead of trying to patch around the fact that short reads can be
legitimate and won't succeed in case of retry, remove the logic to punt
a short read to async context. Simply return it.

vm_ops is now initialized in ib_uverbs_mmap() with the recent rdma mmap
API changes. Earlier it was done in rdma_umap_priv_init() which would not
be called unless a driver called rdma_user_mmap_io() in its mmap.
i40iw does not use the rdma_user_mmap_io API but sets the vma's
vm_private_data to a driver object. This now conflicts with the vm_op
rdma_umap_close as priv pointer points to the i40iw driver object instead
of the private data setup by core when rdma_user_mmap_io is called. This
leads to a crash in rdma_umap_close with a mmap put being called when it
should not have.
Remove the redundant setting of the vma private_data in i40iw as it is not
used. Also move i40iw over to use the rdma_user_mmap_io API. This gives
the extra protection of having the mappings zapped when the context is
detsroyed.

For high-res (8K) or HFR (4K120) displays, using uncompressed pixel
formats like YCbCr444 would exceed the bandwidth of HDMI 2.0, so the
"interesting" modes would be disabled, leaving only low-res or low
framerate modes.
This change lowers the pixel encoding to 4:2:2 or 4:2:0 if the max TMDS
clock is exceeded. Verified that 8K30 and 4K120 are now available and
working with a Samsung Q900R over an HDMI 2.0b link from a Radeon 5700.

DMAR: ACPI name space devices didn't probe correctly
The bug results from the fact that while we now enumerate ACPI devices,
we aren't able to handle any non-PCI device when generating the device
group. Fix the issue by implementing an Intel-specific callback that
returns `pci_device_group` only if the device is a PCI device.
Otherwise, it will return a generic device group.

When userspace requests a video mode parameter value that is not
supported, frame buffer device drivers should round it up to a supported
value, if possible, instead of just rejecting it. This allows
applications to quickly scan for supported video modes.
Currently this rule is not followed for the number of bits per pixel,
causing e.g. "fbset -depth N" to fail, if N is smaller than the current
number of bits per pixel.
Fix this by returning an error only if bits per pixel is too large, and
setting it to the current value otherwise.
See also Documentation/fb/framebuffer.rst, Section 2 (Programmer's View
of /dev/fb*").

In commit 0b8e7bbde5e7 ("drm/sun4i: tcon: Set min division of TCON0_DCLK
to 1.") it was assumed that all TCON variants support a minimum divider
of 1 if only DCLK was used.
However, the oldest generation of hardware only supports minimum divider
of 4 if only DCLK is used. If a divider of 1 was used on this old
hardware, some scrolling artifact would appear. A divider of 2 seemed
OK, but a divider of 3 had artifacts as well.
Set the minimum divider when outputing to parallel RGB based on the
hardware model, with a minimum of 4 for the oldest (A10/A10s/A13/A20)
hardware, and a minimum of 1 for the rest. A value is not set for the
TCON variants lacking channel 0.
This fixes the scrolling artifacts seen on my A13 tablet.
