exynos5433_decon_probe()
When devm_ioremap_resource() fails, a clear enough error message will be
printed by its subfunction __devm_ioremap_resource(). The error
information contains the device name, failure cause, and possibly resource
information.
Therefore, remove the error printing here to simplify code and reduce the
binary size.

"Only a small number of fixes so far, including some that I had applied
during the merge window, so this is based on the original merge of the
other branches.
- The largest change is a fix for a reference counting bug in the AMD

Add Neil as primary maintainer for the Amlogic family of Arm SoCs. I
will now act as co-maintainer.
Neil is already doing lots of the reviewing, testing and behind the
scenes support for users of the upstream kernel on these SoCs, so this
is just to formalize the current state of affairs.
Thanks Neil for all of your efforts, and keep up the great work!

Same Trusted Application (TA) can be loaded in multiple TEE contexts.
If it is a single instance TA, the TA should not get unloaded from AMD
Secure Processor, while it is still in use in another TEE context.
Therefore reference count TA and unload it when the count becomes zero.

The port@0 is a mandatory port, add or move the declaration to the CSI-2
nodes top declared in dtsi files instead of depending on dts files
adding them when describing the external connection.
This fixes validation warnings for DTB outputs that do not connect all
CSI-2 receivers to transmitters and thus declaring all port@0 nodes in
dts files.

Fix the DTS schema by explicitly stating that the input is port@0. This
fixes a schema validation error but has no runtime effect as the default
port number is 0 if not specified.

How the type promotion works in ternary expressions is a bit tricky.
The problem is that scpi_clk_get_val() returns longs, "ret" is a int
which holds a negative error code, and le32_to_cpu() is an unsigned int.
We want the negative error code to be cast to a negative long. But
because le32_to_cpu() is an u32 then "ret" is type promoted to u32 and
becomes a high positive and then it is promoted to long and it is still
a high positive value.
Fix this by getting rid of the ternary.

When driver is loaded after rmmod some drives are not showing up during
discovery.
SATA drives are directly attached to the controller connected phys. During
device discovery, the IDENTIFY command (qc timeout (cmd 0xec)) is timing out
during revalidation. This will trigger abort from host side and controller
successfully aborts the command and returns success. Post this successful
abort response ATA library decides to mark the disk as NODEV.
To overcome this, inside pm8001_scan_start() after phy_start() call, add get
start response and wait for few milliseconds to trigger next phy start.
This millisecond delay will give sufficient time for the controller state
machine to accept next phy start.

API qedf_link_update() is getting called from QED but by that time
shost_data is not initialised. This results in a NULL pointer dereference
when we try to dereference shost_data while updating supported_speeds.
Add a NULL pointer check before dereferencing shost_data.

With the current implementation of the UFS driver active_queues is 1
instead of 0 if all UFS request queues are idle. That causes
hctx_may_queue() to divide the queue depth by 2 when queueing a request and
hence reduces the usable queue depth.
The shared tag set code in the block layer keeps track of the number of
active request queues. blk_mq_tag_busy() is called before a request is
queued onto a hwq and blk_mq_tag_idle() is called some time after the hwq
became idle. blk_mq_tag_idle() is called from inside blk_mq_timeout_work().
Hence, blk_mq_tag_idle() is only called if a timer is associated with each
request that is submitted to a request queue that shares a tag set with
another request queue.
Adds a blk_mq_start_request() call in ufshcd_exec_dev_cmd(). This doubles
the queue depth on my test setup from 16 to 32.
In addition to increasing the usable queue depth, also fix the
documentation of the 'timeout' parameter in the header above
ufshcd_exec_dev_cmd().

Commit 391e2f25601e ("[SCSI] BusLogic: Port driver to 64-bit")
introduced a serious issue for 64-bit systems. With this commit,
64-bit kernel will enumerate 8*15 non-existing disks. This is caused
by the broken CCB structure. The change from u32 data to void *data
increased CCB length on 64-bit system, which introduced an extra 4
byte offset of the CDB. This leads to incorrect response to INQUIRY
commands during enumeration.
Fix disk enumeration failure by reverting the portion of the commit
above which switched the data pointer from u32 to void.

Revert the commit 7a5b96b4784454ba258e83dc7469ddbacd3aaac3 ("dm integrity:
use discard support when recalculating").
There's a bug that when we write some data beyond the current recalculate
boundary, the checksum will be rewritten with the discard filler later.
And the data will no longer have integrity protection. There's no easy
fix for this case.
Also, another problematic case is if dm-integrity is used to detect
bitrot (random device errors, bit flips, etc); dm-integrity should
detect that even for unused sectors. With commit 7a5b96b4784 it can
happen that such change is undetected (because discard filler is not a
valid checksum).

The following commands will crash the kernel:
modprobe brd rd_size=1048576
dmsetup create o --table "0 `blockdev --getsize /dev/ram0` snapshot-origin /dev/ram0"
dmsetup create s --table "0 `blockdev --getsize /dev/ram0` snapshot /dev/ram0 /dev/ram1 N 0"
The reason is that when we test for zero chunk size, we jump to the label
bad_read_metadata without setting the "r" variable. The function
snapshot_ctr destroys all the structures and then exits with "r == 0". The
kernel then crashes because it falsely believes that snapshot_ctr
succeeded.
In order to fix the bug, we set the variable "r" to -EINVAL.

If an origin target has no snapshots, o->split_boundary is set to 0.
This causes BUG_ON(sectors <= 0) in block/bio.c:bio_split().
Fix this by initializing chunk_size, and in turn split_boundary, to
rounddown_pow_of_two(UINT_MAX) -- the largest power of two that fits
into "unsigned" type.

restrack should only be attached to a cm_id while the ID has a valid
device pointer. It is set up when the device is first loaded, but not
cleared when the device is removed. There is also two copies of the device
pointer, one private and one in the public API, and these were left out of
sync.
Make everything go to NULL together and manipulate restrack right around
the device assignments.

The initialization of MIDI devices that are found on some LINE6
drivers are currently done in a racy way; namely, the MIDI buffer
instance is allocated and initialized in each private_init callback
while the communication with the interface is already started via
line6_init_cap_control() call before that point. This may lead to
Oops in line6_data_received() when a spurious event is received, as
reported by syzkaller.
This patch moves the MIDI initialization to line6_init_cap_control()
as well instead of the too-lately-called private_init for avoiding the
race. Also this reduces slightly more lines, so it's a win-win
change.

sampling transfer frequency

channel of data block in CIP payload. Current hard-coded stream format
is wrong.

Avid M-Box 3 Pro
ALSA dice driver detects jumbo payload at high sampling transfer frequency
for below models:
* Avid M-Box 3 Pro
* M-Audio Profire 610
* M-Audio Profire 2626
Although many DICE-based devices have a quirk at high sampling transfer
frequency to multiplex double number of PCM frames into data block than
the number in IEC 61883-1/6, the above devices are just compliant to
IEC 61883-1/6.
This commit disables the mode of double_pcm_frames for the models.

The interrupt handler of intel8x0 calls snd_intel8x0_update() whenever
the hardware sets the corresponding status bit for each stream. This
works fine for most cases as long as the hardware behaves properly.
But when the hardware gives a wrong bit set, this leads to a zero-
division Oops, and reportedly, this seems what happened on a VM.
For fixing the crash, this patch adds a internal flag indicating that
the stream is ready to be updated, and check it (as well as the flag
being in suspended) to ignore such spurious update.
