Subject: [PATCH] drm/rockchip: add PINCTRL dependency for LVDS
Date: Thu, 5 Oct 2017 14:09:39 +0200 [thread overview]
Message-ID: <20171005120957.485433-1-arnd@arndb.de> (raw)
The new driver fails to build when CONFIG_PINCTRL is disabled:
drivers/gpu/drm/rockchip/rockchip_lvds.c: In function 'rockchip_lvds_grf_config':
drivers/gpu/drm/rockchip/rockchip_lvds.c:229:39: error: dereferencing pointer to incomplete type 'struct dev_pin_info'
if (lvds->pins && !IS_ERR(lvds->pins->default_state))
This adds the respective Kconfig dependency.
Fixes: 34cc0aa25456 ("drm/rockchip: Add support for Rockchip Soc LVDS")
