Subject[PATCH] drm/sun4i : constify drm_plane_helper_funcs
Date
drm_plane_helper_funcs are not supposed to change at runtime.
All functions working with drm_plane_helper_funcs provided by
<drm/drm_plane_helper.h> work with const drm_plane_helper_funcs.
So mark the non-const structs as const.

File size before:
text data bss dec hex filename
981 40 0 1021 3fd drivers/gpu/drm/sun4i/sun4i_layer.o

File size After adding 'const':
text data bss dec hex filename
1021 0 0 1021 3fd drivers/gpu/drm/sun4i/sun4i_layer.o
