Subject: drm/stm: ltdc: Remove unnecessary platform_get_resource() error check
Git-commit: eb393dbc8f5b2ca7c87749795fd49b8cf77ab04b
Patch-mainline: v4.16-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166
devm_ioremap_resource() already checks if the resource is NULL, so
remove the unnecessary platform_get_resource() error check.
