Hans Verkuil 314692da7e media: vb2: check memory model for VIDIOC_CREATE_BUFS
commit 62dcb4f418 upstream.

vb2_core_create_bufs did not check if the memory model for newly added
buffers is the same as for already existing buffers. It should return an
error if they aren't the same.

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.
