[PATCH] drm/panthor: avoid garbage value in panthor_ioctl_dev_query()

'priorities_info' is uninitialized, and the uninitialized value is copied to user object when calling PANTHOR_UOBJ_SET(). Using memset to initialize 'priorities_info' to avoid this garbage value problem. Fixes: f7ef2352 ("drm/panthor: Add DEV_QUERY_GROUP_PRIORITIES_INFO dev query") Signed-off
