Subject: [PATCH 85/86] drm/rockchip: add PINCTRL dependency for LVDS

Git-commit: 479b9db27453aea42bfad92e9466135ae063f326
Patch-mainline: Queued
Git-repo: git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git
References: fate#323912

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.
