Janusz Krzysztofik 11e2bcfabe media: ov6650: Fix stored frame format not in sync with hardware
[ Upstream commit 3143b459de4cdcce67b36827476c966e93c1cf01 ]

The driver stores frame format settings supposed to be in line with
hardware state in a device private structure.  Since the driver initial
submission, those settings are updated before they are actually applied
on hardware.  If an error occurs on device update, the stored settings
my not reflect hardware state anymore and consecutive calls to
.get_fmt() may return incorrect information.  That in turn may affect
ability of a bridge device to use correct DMA transfer settings if such
incorrect informmation on active frame format returned by .get_fmt() is
used.

Assuming a failed device update means its state hasn't changed, update
frame format related settings stored in the device private structure
only after they are successfully applied so the stored values always
reflect hardware state as closely as possible.

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.
