Dikshita Agarwal 448a7662ae media: iris: remove v4l2_m2m_ioctl_{de,en}coder_cmd API usage during STOP handling 
[ Upstream commit 8fc707d13d ]

Currently v4l2_m2m_ioctl_{de,enc}coder_cmd is being invoked during STOP
command handling. However, this is not required as the iris driver has
its own drain and stop handling mechanism in place.

Using the m2m command API in this context leads to incorrect behavior,
where the LAST flag is prematurely attached to a capture buffer,
when there are no buffers in m2m source queue. But, in this scenario
even though the source buffers are returned to client, hardware might
still need to process the pending capture buffers.

Attaching LAST flag prematurely can result in the capture buffer being
removed from the destination queue before the hardware has finished
processing it, causing issues when the buffer is eventually returned by
the hardware.

To prevent this, remove the m2m API usage in stop handling.

Fixes: 75db90ae06 ("media: iris: Add support for drain sequence in encoder video device")

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
