Jacopo Mondi 905fa2f2ff media: ov5640: Fix timings setup code 
commit bad1774ed4 upstream.

As of: commit 476dec012f ("media: ov5640: Add horizontal and vertical
totals") the timings parameters gets programmed separately from the
static register values array.

When changing capture mode, the vertical and horizontal totals gets
inspected by the set_mode_exposure_calc() functions, and only later
programmed with the new values. This means exposure, light banding
filter and shutter gain are calculated using the previous timings, and
are thus not correct.

Fix this by programming timings right after the static register value
table has been sent to the sensor in the ov5640_load_regs() function.

Fixes: 476dec012f ("media: ov5640: Add horizontal and vertical totals")

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
