From: Paulo Zanoni Date: Mon, 9 Feb 2015 16:46:29 +0000 (-0200) Subject: drm/i915: change dev_priv->fbc.plane to dev_priv->fbc.crtc X-Git-Tag: firefly_0821_release~176^2~1915^2~35^2~52 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=e35fef211bab1a69da1b392c3ece906e287ed6e4;p=firefly-linux-kernel-4.4.55.git drm/i915: change dev_priv->fbc.plane to dev_priv->fbc.crtc Since the mapping from CRTCs to planes is fixed, looking at the CRTC is essentially the same as looking at the plane. Also, the next patches wil start using the frontbuffer_bits macros, and they take the pipe as the parameter instead of the plane, and this could differ on gens 2 and 3. Another nice thing is that we don't risk accidentally initializing things to PLANE_A if we don't set the value before it is used for the first time. But this shouldn't be a problem with the current code. V2: Rebase.
