The comment blocks at the beginning of each file have a one-line
summary description of the file that includes the file name. While the
description is useful, the file name only creates opportunities for
mistakes (as seen in rcar_du_vsp.c) without any added value. Drop it.

pm_runtime_get_sync will increment pm usage counter even it failed.
Forgetting to putting operation will result in a reference leak here.
A new function pm_runtime_resume_and_get is introduced in [0] to keep
usage counter balanced. So We fix the reference leak by replacing it
with new funtion.

Add a driver for the R-Car Display Unit Color Correction Module.
In most of Gen3 SoCs, each DU output channel is provided with a CMM unit
to perform image enhancement and color correction.
Add support for CMM through a driver that supports configuration of
the 1-dimensional LUT table. More advanced CMM features will be
implemented on top of this initial one.
