Quite often, the HW get stuck in error condition if a stream error
was detected. As documented, the HW should stop immediately and self
reset. There is likely a problem or a miss-understanding of the self
reset mechanism, as unless we make a long pause, the next command
will then report an error even if there is no error in it.
Disabling error detection fixes the issue, and let the decoder continue
after an error. This patch is safe for backport into older kernels.

Commit a1a2b7125e10 ("of/platform: Drop static setup of IRQ resource
from DT core") removed support for calling platform_get_resource(...,
IORESOURCE_IRQ, ...) on DT-based drivers, but the probe() function of
mtk-vcodec's encoder was still making use of it. This caused the encoder
driver to fail probe.
Since the platform_get_resource() call was only being used to check for
the presence of the interrupt (its returned resource wasn't even used)
and platform_get_irq() was already being used to get the IRQ, simply
drop the use of platform_get_resource(IORESOURCE_IRQ) and handle the
failure of platform_get_irq(), to get the driver probing again.

If allocating array_buf fails, or copying data from userspace into that
buffer fails, then just free memory and return the error. Don't attempt
to call video_put_user() since there is no point, and it would copy back
data on error even if INFO_FL_ALWAYS_COPY wasn't set.
So if writing the array back to userspace fails, then don't go to
out_array_args, instead just continue with the regular code that just
returns the error unless 'always_copy' is set.
Update the VIDIOC_G/S/TRY_EXT_CTRLS ioctls to set the ALWAYS_COPY flag
since they now need it. Before this worked due to this buggy code, but
now that that is fixed these ioctls need to set this flag explicitly.

Currently blktests nvme/002 trips up debugobjects if CONFIG_NVME_AUTH is
enabled, but authentication is not on a queue. This is because
nvmet_auth_sq_free cancels sq->auth_expired_work unconditionaly, while
auth_expired_work is only ever initialized if authentication is enabled
for a given controller.
Fix this by calling most of what is nvmet_init_auth unconditionally
when initializing the SQ, and just do the setting of the result
field in the connect command handler.

As per NVMe/TCP transport specification ICReq PDU is the first PDU received
by the controller and controller should receive only one ICReq PDU.
If controller receives more than one ICReq PDU then this can be considered
as fatal error.
nvmet-tcp driver does not check for ICReq PDU opcode if queue state is
NVMET_TCP_Q_LIVE. In LIVE state ICReq PDU is treated as CapsuleCmd PDU,
this can result in abnormal behavior.
Add a check for ICReq PDU in nvmet_tcp_done_recv_pdu() to fix this issue.

means that blk-mq will reinitialize the all the hardware contexts and io

When a discovery controller is disconnected, no AENs will arrive to
notify the host about discovery log change events.
In order to solve this, send a uevent notification when a
persistent discovery controller reconnects. We add a new ctrl
flag NVME_CTRL_STARTED_ONCE that will be set on the first
start, and consecutive calls will find it set, and send the
event to userspace if the controller is a discovery controller.
Upon the event reception, userspace will re-read the discovery
log page and will act upon changes as it sees fit.

The IOC_PR_CLEAR and IOC_PR_RELEASE ioctls are
non-functional on NVMe devices because the nvme_pr_clear()
and nvme_pr_release() functions set the IEKEY field incorrectly.
The IEKEY field should be set only when the key is zero (i.e,
not specified). The current code does it backwards.
Furthermore, the NVMe spec describes the persistent
reservation "clear" function as an option on the reservation
release command. The current implementation of nvme_pr_clear()
erroneously uses the reservation register command.
Fix these errors. Note that NVMe version 1.3 and later specify
that setting the IEKEY field will return an error of Invalid
Field in Command. The fix will set IEKEY when the key is zero,
which is appropriate as these ioctls consider a zero key to
be "unspecified", and the intention of the spec change is
to require a valid key.
Tested on a version 1.4 PCI NVMe device in an Azure VM.

If a reset occurs after the scan work attempts to issue a command, the
reset may quisce the admin queue, which blocks the scan work's command
from dispatching. The scan work will not be able to complete while the
queue is quiesced.
Meanwhile, the reset work will cancel all outstanding admin tags and
wait until all requests have transitioned to idle, which includes the
passthrough request. But the passthrough request won't be set to idle
until after the scan_work flushes, so we're deadlocked.
Fix this by handling the end effects after the request has been freed.

As noted by Arnd Bergmann, "we used to have three drivers for the same
hardware (pcmcia, pata and ide), and only the pcmcia driver remained
in the tree after drivers/ide/ was removed and pata_at91 did not get
converted to DT". "There is no dts file in tree that actually declares
either of them, so chances are that nobody is actually using the CF
slot on at91 any more."[1]
On this rationale, remove the AT91RM9200 Compact Flash driver, which
also assists in reaching "the goal of stopping exporting OF-specific
APIs of gpiolib".[2]

The bug is here: "} else if (item) {".
The list iterator value will *always* be set and non-NULL by
list_for_each_entry(), so it is incorrect to assume that the iterator
value will be NULL if the list is empty or no element is found in list.
Use a new value 'iter' as the list iterator, while use the old value
'item' as a dedicated pointer to point to the found element, which
1. can fix this bug, due to now 'item' is NULL only if it's not found.
2. do not need to change all the uses of 'item' after the loop.
3. can also limit the scope of the list iterator 'iter' *only inside*
the traversal loop by simply declaring 'iter' inside the loop in the
future, as usage of the iterator outside of the list_for_each_entry
is considered harmful. https://lkml.org/lkml/2022/2/17/1032

The qcom2260 and sm6115 GCC drivers use a common modified DEFAULT and
BRAMMO alpha pll offsets. Move these common offsets to the shared place
to avoid duplication. The new layouts have a suffix EVO similar to LUCID
and RIVIAN.

The DEFAULT and BRAMMO PLL offsets are non-standard in downstream, but
currently only BRAMMO ones are overridden. Override DEFAULT ones too.
A very similar thing is happening in gcc-qcm2290 driver.
