Sebastian Fricke 103d15bc20 media: v4l2: Add ignore_streaming flag
Add a new flag to the `struct v4l2_m2m_dev` to toggle whether a queue
must be streaming in order to allow queuing jobs to the ready queue.
Currently, both queues (CAPTURE & OUTPUT) must be streaming in order to
allow adding new jobs. This behavior limits the usability of M2M for
some drivers, as these have to be able, to perform analysis of the
sequence to ensure, that userspace prepares the CAPTURE queue correctly.

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 Restructured Text 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.
