This bit enables replication logic to expand an RGB color less than 24
bits, to 24 bits, which is used internally for all formats. Otherwise,
the least significant bits are always set to zero and the color may not
be what is expected.

Thanks - this gave me an opportunity to read a bit more in the datasheet
of the controller.
Applied to drm-misc-next with Ack from Nicolas.

I was about to add my R-b and ask you to apply the patch :-). I'm glad
you didn't wait for my feedback to apply the fix, that means I'll be
able to remove my name from the Atmel HLCDC entry soon ;-).

Was about to add my R-b and ask you to apply the patch. I'm glad you
didn't wait for my feedback though, that means I'll soon be able to
remove my name from the Atmel HLCDC entry in MAINTAINERS ;-).
