From: Bhumika Goyal Date: Tue, 8 Aug 2017 20:35:51 +0530 Subject: drm: make drm_mode_config_func const Git-commit: a5cb37d800a49922fdd80a20384b55b4a6b7bece Patch-mainline: v4.14-rc1 References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166 Make these structures const as they are only stored in the funcs field of a drm_mode_config structure which is of type const.
