When attempting to change the white balance (WB) ctrls before starting
streaming, e.g.:
# v4l2-ctl -L
User Controls
..
blue_component_gain 0x009819c1 (int) : min=0 max=8191 step=1 default=512 value=512 flags=slider
..
# v4l2-ctl --set-ctrl=blue_component_gain=500
# v4l2-ctl -L
..
blue_component_gain 0x009819c1 (int) : min=0 max=8191 step=1 default=512 value=500 flags=slider
..
These will not be written to the internal data struct and will not be
written to the WB hardware module.
Thus, after starting streaming, they will be reset to default:
# v4l2-ctl -L
..
blue_component_gain 0x009819c1 (int) : min=0 max=8191 step=1 default=512 value=512 flags=slider
..
It does not make much sense to not be able to configure the WB controls
at all times. Even if the sensor would not be RAW Bayer (and in this case the
WB module is unavailable), the user could configure the ISC itself, as the
ISC should not care about the sensor format.
Thus, when WB module is available (if the sensor changes format e.g.) it will
be already configured as be user's desires.
In consequence, remove the check in isc_s_awb_ctrl that will return if ISC
does not know the sensor format.

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.
