Subject: drm/i915: Pass in plane state when (un)pinning frame buffers
X-Git-Tag: firefly_0821_release~176^2~1470^2~58^2~221
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=82bc3b2daa78d99b5c93ef17e8b660e56447c935;p=firefly-linux-kernel-4.4.55.git

drm/i915: Pass in plane state when (un)pinning frame buffers

Plane state carries the rotation information which is needed for determining
the appropriate GGTT view type.

This just adds the parameter with the actual usage coming in future patches.
