  [PATCH] drm: armada: constify drm_prop_enum_list structures. Arvind Yadav <arvind.yadav.cs@gmail.com> - 2017-07-01 12:10 +0200

#1679325 — [PATCH] drm: armada: constify drm_prop_enum_list structures.

drm_prop_enum_lists are not supposed to change at runtime. All functions
working with drm_prop_enum_list provided by <drm/drm_property.h> work
with
const drm_prop_enum_list. So mark the non-const structs as const.

File size before:
   text	   data	    bss	    dec	    hex	filename
   9629	    744	      0	  10373	   2885 drivers/gpu/drm/armada/armada_crtc.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
   9757	    616	      0	  10373	   2885 drivers/gpu/drm/armada/armada_crtc.o
