mainlining shenanigans
1463b371af
The driver stores crop rectangle settings supposed to be in line with
hardware state in a device private structure. Since the driver initial
submission, crop rectangle width and height settings are not updated
correctly when rectangle offset settings are applied on hardware. If
an error occurs while the device is updated, the stored settings my no
longer reflect hardware state and consecutive calls to .get_selection()
as well as .get/set_fmt() may return incorrect information. That in
turn may affect ability of a bridge device to use correct DMA transfer
settings if such incorrect informamtion on active frame format returned
by .get/set_fmt() is used.
Assuming a failed update of the device means its actual settings haven't
changed, update crop rectangle width and height settings stored in the
device private structure correctly while the rectangle offset is
successfully applied on hardware so the stored values always reflect
actual hardware state to the extent possible.

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.
