From 82581fcf070b68a91fb3a3ade08d9a76380a4789 Mon Sep 17 00:00:00 2001 From: Philipp Zabel Date: Fri, 8 Jan 2021 10:53:06 +0100 Subject: [PATCH] drm/modes: add non-OF stub for of_get_drm_display_mode If CONFIG_OF is disabled, of_get_drm_display_mode is not compiled in, and drivers using it fail to build: ld: drivers/gpu/drm/imx/parallel-display.o: in function `imx_pd_connector_get_modes': parallel-display.c:(.text+0x8d): undefined reference to `of_get_drm_display_mode' Add an inline stub so they can be build-tested with non-OF configurations.
