Subject[PATCH -next] drm/arc: Fix some sparse warnings
Date
From: Wei Yongjun <yongjun_wei@trendmicro.com.cn>

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?
