Subject: drm: sti: sti_dvo: make of_device_ids const.
Git-commit: 6daac7990a4451f68400068aa97254b8e4f8d977
Patch-mainline: v4.14-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166
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.
