Algea Cao 38e112d31c drm/bridge: synopsys: dw-hdmi: Check whether color has changed in connector atomic_check
For compatibility with GKI, connector atomic_begin/atomic_flush should
be removed. If hdmi color format has changed, set flag mode_changed
true and start a modeset to config hdmi.

We check whether color format has changed in
dw_hdmi_connector_atomic_check(), but color format variable update in
dw_hdmi_rockchip_encoder_atomic_check(), It runs after
dw_hdmi_connector_atomic_check(). That will lead to misjudgments when
determining whether color format has changed.

To solve this problem, we introduce get_color_changed(). When color
properties are set and color format is changed, get_color_changed()
return true.

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.
