Subject: [PATCH] drm/panel: rm68200: add backlight dependency
Date: Tue, 13 Mar 2018 21:59:54 +0100 [thread overview]
Message-ID: <20180313210015.3344380-1-arnd@arndb.de> (raw)
Like many other panel drivers, this one fails to build
when backlight support is disabled:
drivers/gpu/drm/panel/panel-raydium-rm68200.o: In function `rm68200_probe':
panel-raydium-rm68200.c:(.text+0x14a): undefined reference to `devm_of_find_backlight'
This adds the appropriate dependency.
Fixes: 2b7ed18bed1a ("drm/panel: Add support for Raydium RM68200 panel driver")

Say Y here if you want to enable support for Raydium RM68200
720x1280 DSI video mode panel.
