drm/arc: Fix some sparse warnings
Fixes the following sparse warnings: drivers/gpu/drm/arc/arcpgu_drv.c:52:5: warning: symbol 'arcpgu_gem_mmap' was not declared. Should it be static? drivers/gpu/drm/arc/arcpgu_drv.c:134:48: warning: Using plain integer as NULL pointer drivers/gpu/drm/arc/arcpgu_drv.c:155:5: warning: symbol 'arcpgu_unload' was not declared. Should it be static? Signed-off-by: Wei Yongjun <yongjun_wei@trendmicro.com.cn> Signed-off-by: Sean Paul <seanpaul@chromium.org>
