From: Ville Syrjälä Date: Wed, 24 Jun 2015 18:59:34 +0000 (+0300) Subject: drm/i915: Store frontbuffer_bits in the plane X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a9ff8714d911b1f9417af75525eb29ac31e014fc;p=linux-beck.git drm/i915: Store frontbuffer_bits in the plane Avoid some 'switch (plane->type)' by storing the fronbuffer_bits in intel_plane. Signed-off-by: Ville Syrjälä [danvet: use singular frontbuffer_bits in intel_plane since a plan can only ever have one bit.
