Subject: drm/atmel-hlcdc : constify drm_plane_helper_funcs and drm_plane_funcs.
Git-commit: d95a8e7b2ac31029fd916711dff3bf9c562da700
Patch-mainline: v4.14-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166
drm_plane_helper_funcs and drm_plane_funcsare not supposed to change
at runtime. All functions working with drm_plane_helper_funcs and
drm_plane_funcs work with const. So mark the non-const structs as const.

File size After adding 'const':
