Janusz Krzysztofik 08ba731d67 media: ov6650: Fix stored frame interval not in sync with hardware
[ Upstream commit 57822068dd120386b98891cb151dc20107b63ba7 ]

The driver stores a frame interval value supposed to be in line with
hardware state in a device private structure.  Since the driver initial
submission, the respective field of the structure has never been
initialised on device probe.  Moreover, if updated from
.s_frame_interval(), a new value is stored before it is applied on
hardware.  If an error occurs during device update, the stored value
may no longer reflect hardware state and consecutive calls to
.g_frame_interval() may return incorrect information.

Assuming a failed update of the device means its actual state hasn't
changed, update the frame interval field of the device private
structure with a new value only after it is successfully applied on
hardware so it always reflects actual hardware state to the extent
possible.  Also, initialise the field with hardware default frame
interval on device probe.

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.
