Subject[PATCH] drm: exynos: hdmi: make of_device_ids const.
Date
of_device_ids are not supposed to change at runtime. All functions
working with of_device_ids provided by <linux/of.h> work with const
of_device_ids. So mark the non-const structs as const.

File size before:
text data bss dec hex filename
12294 1192 0 13486 34ae drivers/gpu/drm/exynos/exynos_hdmi.o

File size after constify hdmi_match_types.
text data bss dec hex filename
13318 176 0 13494 34b6 drivers/gpu/drm/exynos/exynos_hdmi.o
