Colin Ian King 1df8f8901b drm/v3d: Fix null pointer dereference of pointer perfmon ... [ Upstream commit ce7a1ecf3f ] In the unlikely event that pointer perfmon is null the WARN_ON return path occurs after the pointer has already been deferenced. Fix this by only dereferencing perfmon after it has been null checked.
