[PATCH v4 16/17] drm/i915/display: Use the general "Broadcast RGB" implementation

Werner Sembach wse at tuxedocomputers.com
Fri Jun 18 09:11:15 UTC 2021


Change from the i915 specific "Broadcast RGB" drm property implementation
to the general one.

This commit delete all traces of the former "Broadcast RGB" implementation
and add a new one using the new driver agnoistic functions an variables.
