My patch with commit 2dccc9898d45 is for Linux 4.0-rcN. It has no 
relationship
 with linux-next since Matt Roper's afd65eb4cc05 has solved this long 
long ago.

So, 2dccc9898d45 should not be tagged with for-linux-next-fixes (in 
repository
http://cgit.freedesktop.org/drm-intel/). I think it caused the mess of 
version
control.

BTW, there is still one thing should be done in linux-next. We should 
change
Matt's update_state_fb to use drm_atomic_set_fb_for_plane since the logic of
Matt's code is duplicated with drm_atomic_set_fb_for_plane.
