This patch adds a BACKLIGHT_CLASS_DEVICE dependency to configure the DRM_SHMOBILE. Without this patch, build system can lead to build failure. This was observed during randconfig testing, in which DRM_SHMOBILE was enabled w/o BACKLIGHT_CLASS_DEVICE being enabled. Following was the error: Building modules, stage 2.
