Subject: [PATCH 3/3] drm/panel: add backlight dependency for sitronix-st7789v
Date: Wed, 19 Apr 2017 20:03:08 +0200 [thread overview]
Message-ID: <20170419180326.303994-1-arnd@arndb.de> (raw)
In-Reply-To: <20170419175939.189098-2-arnd@arndb.de>
Without the dependency, we run into a link error:
drivers/gpu/drm/panel/panel-sitronix-st7789v.o: In function `st7789v_probe':
panel-sitronix-st7789v.c:(.text.st7789v_probe+0xc0): undefined reference to `of_find_backlight_by_node'
Fixes: 7142afb3a186 ("drm/panel: Add driver for sitronix ST7789V LCD controller")

Say Y here if you want to enable support for the Sitronix
