From: Laurent Pinchart Date: Tue, 15 May 2018 18:57:36 +0300 Subject: drm: rcar-du: Fix rcar_du_of_init() stub Git-commit: dd856d924b2471bf28e7c60df881529525a1192c Patch-mainline: v4.18-rc1 References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166 The rcar_du_of_init() function is supposed to be defined as a stub when CONFIG_DRM_RCAR_LVDS is disabled as the rcar_du_of.c file isn't compiled in that case. However, a bug in the configuration option check makes it a stub when CONFIG_DRM_RCAR_LVDS=m as well, which prevents legacy DTs from being fixed at boot time. Fix the configuration option check by using IS_ENABLED.
