Subject: drm/omap: constify attribute_group structures.
Git-commit: b68ed480d50f405c8f79ac646bbc2f6ac91f9e62
Patch-mainline: v4.14-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166
attribute_groups are not supposed to change at runtime. All functions
working with attribute_groups provided by <linux/sysfs.h> work with const
attribute_group. So mark the non-const structs as const.
