Hans Verkuil 1f7f11e8ca media: videobuf2-v4l2.c: move up STATE_DEQUEUED check
If a buffer is queued to a request, followed by an attempt to queue
the same buffer again, then the second qbuf returns an error since
the buffer is not in the DEQUEUED state anymore.

However, before it gets to that check it executes the code under the
'if (!vb->prepared)' condition. This clears previously set data needed
for request handling, and now querybuf will no longer report that this
buffer is part of a request.

Move the state check to before the 'if' and make sure to only do the
state check when called from QBUF and if V4L2_BUF_FLAG_REQUEST_FD is
set.

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.
