The existing implementation for the get_feature admin-cmd does not
use per-feature data len. This patch introduces a new helper function
nvmet_feat_data_len(), which is used to calculate per feature data len.
Right now we only set data len for fid 0x81 (NVME_FEAT_HOST_ID).

It appears that the drivers does not go into power save correctly the
NULL data packets are not being transmitted because it not enabled
in mac80211.
The driver needs to capture ieee80211_is_nullfunc headers and
copy the duration_id to it's own duration data header.

It appears that the driver still transmits in CTS protect mode even
though it is not enabled in mac80211.
That is both packet types PK_TYPE_11GA and PK_TYPE_11GB both use CTS protect.
The only difference between them GA does not use B rates.
Find if only B rate in GB or GA in protect mode otherwise transmit packets
as PK_TYPE_11A.

Jonathan writes:
First set of new device support, features and cleanups for IIO in the 5.6 cycle
New device support
* ad7091r5 ADC
- New driver with follow up patch adding scale and vref support.
- DT bindings
* ad7923
- Support for ad7908, ad7918 and ad7928 added to driver.
* bma180
- Support the BMA254 accelerometer. Required fairly substantial rework
to allow for small differences between this an existing parts.
* bma400 accelerometer
- New driver with follow up patch for regulator support.
- DT bindings.
* asc dlhl60d
- New driver support this range of pressure and temperature sensors.
- DT bindings.
* ltc2496 ADC
- New driver to support this ADC.
- Split the existing LTC2497 driver generic component out and reuse.
- DT bindings.
* parallax ping
- New driver supporting ultrasonic and laser tof distance sensors.
- Bindings for these sensors.
New features
* core
- New char type for read_raw returns, used for thermocouple types.
- Rename read_first_n callback to read. The reasons behind the original
naming are lost to the mists of time.
* ad799x
- Allow pm_ops to disable device completely allowing regulator power down.
* bma180
- Enable basic regulator support.
* dmaengine buffer
- Report platform data alignment requirements via new ABI.
* max31856
- Add option to set mains filter rejection frequency and document
new in_temp_filter_notch_center_frequency ABI.
- Add support for configuring HW averaging (oversampling ratio)
- Add runtime configuration of thermocouple type and document new ABI.
* maxim-thermocouple
- Add read only access to thermocouple type using new ABI, includes
adding more specific compatibles to reflect which variant of the
chip is being used.
* mpu6050
- Provide option to support the PMU9150 in package magnetometer directly
rather than via auxiliary bus.
* stm32_adc
- Add overrun interrupt checks to detect if this happens.
* st_lsm6dsx
- Enable the sensor-hub support for lsm6dsm. Includes various reworks to
allow this.
Cleanups and minor fixes
* Subsystem wide
- Tidy up indentation in Kconfig and fix alphabetical order of AD7091R5.
- Drop linux/gpio.h and linux/of_gpio.h from drivers that don't use them.
* ad7266
- Convert to GPIO descriptors.
* ad7303
- Avoid a dance with checking if the regulator is supplied by just
using the optional request interface.
* ad7887
- Simplify channel specification assignment to enable adding more devices.
* ad7923
- Drop some unused and largely pointless defines of BOB_N==N variety.
- Tidy up checkpatch warnings.
- Add missing of_device_id table.
* adf4350
- Convert to GPIO descriptors.
* ak8975
- Convert to GPIO descriptors.
* ADIS library and drivers
- Expand scope of txrx_lock to cover all state and rename as state_lock
- Add unlocked read / write to allow grouping of consecutive calls under
single lock / unlock.
- Add unlocked check_status, reset to allow grouping under single
lock / unlock.
- Remove remaining uses of core mlock for local state protection.
mlock should never be used directly as it protects tightly defined
core IIO device management state.
* adis16240
- Enforce only supported SPI mode on driver load + add DT binding doc.
* atlas-ph-sensor
- Rename to atlas-sensor given it now covers things beyond ph sensors.
* bma180
- Use local dev variable to tidy up code.
- Use c99 style explicity .member assignment to make driver more readable.
* bmp280
- Drop ACPI support. No evidence this was used and appropriate ID is not
registered.
- Allow ACPI to bind device via PRP0001
* dmaengine buffer
- Use dma_request_chan instead of dma_request_slave_channel_reason as that
ABI is going away.
- Add module info to avoid tainting the kernel.
* hts221
- Avoid magic number defines when only used to fill structure elements
that are self describing.
* lm3533
- Drop a stray semicolon.
* max9611
- Cleanup enum handling to be more resilient to future changes.
* mpu6050
- Delete MPU9150 from supported SPI devices as doesn't provide SPI.
- Select I2C_MUX again after kbuild issue fixed elsewhere.
* stm32-timer
- Drop an unnecessary register update.
* ssp_sensors
- Convert to GPIO descriptors.
* st_sensors
- drop !CONFIG_ACPI defines as ACPI_PTR() will stop them being used
anyway.
- Make default platform data structures __maybe_unsued.
- Fill in some missing kernel-doc function parameters.
* st_lsm6dsx
- white space fixes.
- Mark some constants that aren't always used as __maybe_unused.
- Drop of ID table guards as they just pervent use under ACPI.
- Switch to device properties to allow ACPI usage.
* st_uvis25
- Drop acpi.h include as no ACPI APIs used.
* ti-ads1015
- Drop legacy platform data as no one seems to be using it.
- Use the device property API instead of OF specific.
* ti-ads7950
- typo fix in error message.

The I2C specification states that tsu:sto for standard mode timing must
be at minimum 4us. Pictographically, this is:
SCL: ____/~~~~~~~~~
SDA: _________/~~~~
->| |<- 4us minimum
We are currently waiting 2.5us between asserting SCL and SDA, which is
in violation of the standard. Adjust the timings to ensure that we meet
what is stipulated as the minimum timings to ensure that all devices
correctly interpret the STOP bus transition.
This is more important than trying to generate a square wave with even
duty cycle.

(01h) command, the chip select should be driven LOW and held LOW until
the eighth bit of the last data byte has been latched in, after which
it must be driven HIGH. If CS is not driven HIGH, the command is not
executed, flag status register error bits are not set, and the write enable
latch remains set to 1. This fixes the lock operations on micron flashes.

We are currently using nand_soft_waitrdy to poll the status of the NAND
flash. FMC2 enables the wait feature bit (this feature is mandatory for
the sequencer mode). By enabling this feature, we can't poll the status
of the NAND flash, the read status command is stucked in FMC2 pipeline
until R/B# signal is high, and locks the CPU bus.
To avoid to lock the CPU bus, we poll FMC2 ISR register. This register
reports the status of the R/B# signal.

Commit 85a8ce62c2ea ("block: add bio_truncate to fix guard_bio_eod")
adds bio_truncate() for handling bio EOD. However, bio_truncate()
doesn't use the passed 'op' parameter from guard_bio_eod's callers.
So bio_trunacate() may retrieve wrong 'op', and zering pages may
not be done for READ bio.
Fixes this issue by moving guard_bio_eod() after bio_set_op_attrs()
in submit_bh_wbc() so that bio_truncate() can always retrieve correct
op info.
Meantime remove the 'op' parameter from guard_bio_eod() because it isn't
used any more.

The `connected` value for wired devices was not properly initialized,
it must be set to `true` upon creation, because wired devices do not
generate connection events.
When a raw client (the Steam Client) uses the device, the input device
is destroyed. Then, when the raw client finishes, it must be recreated.
But since the `connected` variable was false this never happended.

In my attempt to fix a memory leak, I introduced a double-free in the
pstore error path. Instead of trying to manage the allocation lifetime
between persistent_ram_new() and its callers, adjust the logic so
persistent_ram_new() always takes a kstrdup() copy, and leaves the
caller's allocation lifetime up to the caller. Therefore callers are
_always_ responsible for freeing their label. Before, it only needed
freeing when the prz itself failed to allocate, and not in any of the
other prz failure cases, which callers would have no visibility into,
which is the root design problem that lead to both the leak and now
double-free bugs.

The current 'tipc_wait_for_connect()' function does a wait-loop for the
condition 'sk->sk_state != TIPC_CONNECTING' to conclude if the socket
connecting has done. However, when the condition is met, it returns '0'
even in the case the connecting is actually failed, the socket state is
set to 'TIPC_DISCONNECTING' (e.g. when the server socket has closed..).
This results in a wrong return code for the 'connect()' call from user,
making it believe that the connection is established and go ahead with
building, sending a message, etc. but finally failed e.g. '-EPIPE'.
This commit fixes the issue by changing the wait condition to the
'tipc_sk_connected(sk)', so the function will return '0' only when the
connection is really established. Otherwise, either the socket 'sk_err'
if any or '-ETIMEDOUT'/'-EINTR' will be returned correspondingly.

When a socket is suddenly shutdown or released, it will reject all the
unreceived messages in its receive queue. This applies to a connected
socket too, whereas there is only one 'FIN' message required to be sent
back to its peer in this case.
In case there are many messages in the queue and/or some connections
with such messages are shutdown at the same time, the link layer will
easily get overflowed at the 'TIPC_SYSTEM_IMPORTANCE' backlog level
because of the message rejections. As a result, the link will be taken
down. Moreover, immediately when the link is re-established, the socket
layer can continue to reject the messages and the same issue happens...
The commit refactors the '__tipc_shutdown()' function to only send one
'FIN' in the situation mentioned above. For the connectionless case, it
is unavoidable but usually there is no rejections for such socket
messages because they are 'dest-droppable' by default.
In addition, the new code makes the other socket states clear
(e.g.'TIPC_LISTEN') and treats as a separate case to avoid misbehaving.

LINENO attr present:
