From 4a96f3d05668cdee90779b07227054d4ec41b32d Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 5 Oct 2017 14:06:41 +0200 Subject: [PATCH] drm/omap: displays: panel-dpi: add backlight dependency [ Upstream commit 499ec0ed5eb2f6a7fcaab2dd66ffc5993484bda9 ] The new backlight code causes a link failure when backlight support itself is disabled: drivers/gpu/drm/omapdrm/displays/panel-dpi.o: In function `panel_dpi_probe_of': panel-dpi.c:(.text+0x35c): undefined reference to `of_find_backlight_by_node' This adds a Kconfig dependency like we have for the other OMAP display targets.
