[ Upstream commit 914941827aad5ecddf9bf3a6dee67fbec1af1fff ] This fixes several issues found with 'v4l2-compliance -s': 1) read()/write() is supported, but not reported in the capabilities 2) S_STD(G_STD()) failed: setting the same standard should just return 0. 3) G_PARM failed to set readbuffers. 4) different field values in the format vs. what v4l2_buffer reported. 5) zero the sequence number when starting streaming. 6) drop VB_USERPTR: makes no sense with dma_contig streaming.

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.
