linux-next: build warnings after merge of the drm tree

Hi Dave,

After merging the drm tree, today's linux-next build (x86_64 allmodconfig)
produced these warnings:

drivers/gpu/drm/gma500/backlight.c:29:13: warning: 'do_gma_backlight_set' defined but not used [-Wunused-function]
drivers/gpu/drm/nouveau/core/subdev/gpio/base.c: In function 'nouveau_gpio_isr_del':
drivers/gpu/drm/nouveau/core/subdev/gpio/base.c:219:4: warning: 'flush_work_sync' is deprecated (declared at include/linux/workqueue.h:448) [-Wdeprecated-declarations]
drivers/gpu/drm/nouveau/nouveau_drm.c: In function 'nouveau_drm_open':
drivers/gpu/drm/nouveau/nouveau_drm.c:503:2: warning: format '%d' expects argument of type 'int', but argument 4 has type 'struct pid *' [-Wformat]
