Subject: [PATCH 1/3] drm/omap: displays: panel-dpi: add backlight dependency
Date: Wed, 19 Apr 2017 19:59:17 +0200 [thread overview]
Message-ID: <20170419175939.189098-1-arnd@arndb.de> (raw)
The panel driver gained support for backlight but fails to link now
when that is disabled:
drivers/gpu/drm/omapdrm/displays/panel-dpi.o: In function `panel_dpi_probe_of':
panel-dpi.c:(.text.panel_dpi_probe_of+0xe8): undefined reference to `of_find_backlight_by_node'
This adds a dependency like we have for the other panel drivers.
Fixes: 39135a305a0f ("drm/omap: displays: panel-dpi: Support for handling backlight devices")
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
