Subject: drm/i915: Make setting color key atomic.
X-Git-Tag: omap-for-v4.3/fixes-rc1~89^2~36^2~252
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=818ed961e6ee7988829918b5dc41da14a05f5bc5;p=pandora-kernel.git

drm/i915: Make setting color key atomic.

By making color key atomic there are no more transitional helpers.
The plane check function will reject the color key when a scaler is
active.
