Subject: [PATCH v4 16/17] drm/i915/display: Use the general "Broadcast RGB" implementation
Date:   Fri, 18 Jun 2021 11:11:15 +0200
Message-Id: <20210618091116.14428-17-wse@tuxedocomputers.com>

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.
