Hi all,

After merging the drm-misc tree, today's linux-next build (arm
multi_v7_defconfig) failed like this:

drivers/gpu/drm/msm/mdp/mdp5/mdp5_plane.c: In function 'mdp5_plane_cleanup_fb':
drivers/gpu/drm/msm/mdp/mdp5/mdp5_plane.c:272:26: error: 'fb' redeclared as different kind of symbol
struct drm_framebuffer *fb = old_state->fb;
^
drivers/gpu/drm/msm/mdp/mdp5/mdp5_plane.c:267:27: note: previous definition of 'fb' was here
struct drm_framebuffer *fb,
^
drivers/gpu/drm/msm/mdp/mdp5/mdp5_plane.c: At top level:
drivers/gpu/drm/msm/mdp/mdp5/mdp5_plane.c:383:3: warning: initialization from incompatible pointer type
.cleanup_fb = mdp5_plane_cleanup_fb,
^
drivers/gpu/drm/msm/mdp/mdp5/mdp5_plane.c:383:3: warning: (near initialization for 'mdp5_plane_helper_funcs.cleanup_fb')

Caused by commit

a317290af0db ("drm/atomic: Make prepare_fb/cleanup_fb only take state, v3")

Well, that was clearly never build tested :-(

I have used the drm-misc tree from next-20150902 for today.
