[PATCH] drm/radeon:avoid null pointer dereference when dev is not bound

[Why] Similar to commit<0fa375e6>. If the set_state/can_switch code access the drm_device when dev is not bound, a null pointer dereference can happen. [How] Add sanity checks to prevent it. Signed-off-by: Defang Bo --- drivers/gpu/drm/radeon/radeon_device.c | 6 ++ 1 file changed, 6 inser
