Please give drm-fixes a spin, specifically:

commit 8218c3f4df3bb1c637c17552405039a6dd3c1ee1
Author: Daniel Vetter <daniel.vetter at ffwll.ch>
Date:   Fri Feb 27 12:58:13 2015 +0100

    drm: Fixup racy refcounting in plane_force_disable

http://cgit.freedesktop.org/~airlied/linux/commit/?h=drm-fixes&id=8218c3f4df3bb1c637c17552405039a6dd3c1ee1

Accidentally this landed in drm-next instead of -fixes at first.

Thanks, Daniel
