[PATCH 1/1] drm: avoid exposing kernel stack in compat_drm_getstats

The C standard does not specify the size of the integer used to store an enum. Hence in structure drm_stats32_t alignment bytes may exist. To avoid exposing bytes from the kernel stack it is necessary to initialize variable s32 completely. Signed-off-by: Heinrich Schuchardt ---
