Nicolas Dufresne 3a99c44741 media: rkvdec: Disable H.264 error detection
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.

Nícolas F. R. A. Prado a2d2e593d3 media: mediatek: vcodec: Drop platform_get_resource(IORESOURCE_IRQ)
Commit a1a2b7125e ("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.

Hans Verkuil f0da34f329 media: v4l2-ioctl.c: fix incorrect error path
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

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

If controller receives more than one ICReq PDU then this can be considered

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.

Keith Busch 6ee742fa8e nvme-pci: report the actual number of tagset maps
We've been reporting 2 maps regardless of whether the module parameter
asked for anything beyond the default queues. A consequence of this
means that blk-mq will reinitialize the all the hardware contexts and io
schedulers on every controller reset when the mapping is exactly the
same as before. This unnecessary overhead is adding several milliseconds
on a reset for environments that don't need it. Report the actual number
of mappings in use.

Sagi Grimberg f46ef9e87c nvme: send a rediscover uevent when a persistent discovery controller reconnects
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.

Michael Kelley c292a337d0 nvme: Fix IOC_PR_CLEAR and IOC_PR_RELEASE ioctls for nvme devices
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.

Keith Busch bc8fb906b0 nvme: handle effects after freeing the request
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.

Takashi Iwai f0061c18c1 ALSA: pcm: Avoid reference to status->state
In the PCM core and driver code, there are lots place referring to the
current PCM state via runtime->status->state.  This patch introduced a
local PCM state in runtime itself and replaces those references with
runtime->state.  It has improvements in two aspects:

- The reduction of a indirect access leads to more code optimization

- It avoids a possible (unexpected) modification of the state via mmap
  of the status record

The status->state is updated together with runtime->state, so that
user-space can still read the current state via mmap like before,
too.

This patch touches only the ALSA core code.  The changes in each
driver will follow in later patches.
