linux-next: build warning after merge of the amdgpu tree

Hi all,

After merging the amdgpu tree, today's linux-next build (htmldocs)
produced this warning:

include/drm/drm_atomic.h:908: warning: Function parameter or member '__state' not described in 'for_each_new_plane_in_state_reverse'
include/drm/drm_atomic.h:908: warning: Function parameter or member 'plane' not described in 'for_each_new_plane_in_state_reverse'
include/drm/drm_atomic.h:908: warning: Function parameter or member 'new_plane_state' not described in 'for_each_new_plane_in_state_reverse'
include/drm/drm_atomic.h:908: warning: Function parameter or member '__i' not described in 'for_each_new_plane_in_state_reverse'

Introduced by commit

  a6c3c37b661d ("drm/amd/display: fix gcc set but not used warning of variable 'old_plane_state'")
