Like many other panel drivers, this one fails to build when backlight
support is disabled:
drivers/gpu/drm/panel/panel-raydium-rm68200.o: In function `rm68200_probe':
panel-raydium-rm68200.c:(.text+0x14a): undefined reference to `devm_of_find_backlight'
This adds the appropriate dependency.
Note that while include/linux/backlight.h provides a stub inline when
backlight support is not enabled, this isn't enough to deal with the
case where backlight support is built as a module but the panel driver
is built-in, in which case linking will still fail as above.
One way to avoid this is to add a dependency such as this:
depends on BACKLIGHT_CLASS_DEVICE || BACKLIGHT_CLASS_DEVICE=n
but that is rather complex and misses the point that the panel support
is mostly useless without backlight support.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
