Hans Verkuil b7ff0b0990 media: vb2: skip request checks for VIDIOC_PREPARE_BUF 
VIDIOC_PREPARE_BUF should ignore V4L2_BUF_FLAG_REQUEST_FD since it isn't
doing anything with requests. So inform vb2_queue_or_prepare_buf whether
it is called from vb2_prepare_buf or vb2_qbuf and just return 0 in the
first case.

This was found when adding new v4l2-compliance checks.

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.
