Ezequiel Garcia 913f3ec280 media: mem2mem: Require capture and output mutexes to match
Currently, all the mem2mem driver either use a single mutex
to lock the capture and output videobuf2 queues, or don't
set any mutex.

This means the mutexes match, and so the mem2mem framework
is able to set the m2m context lock.

Enforce this by making it mandatory for drivers to set
the same capture and output mutex, or not set any mutex at all.

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 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.
