4.2.8-ckt5 -stable review patch. If anyone has any objections, please let me know. ---8<------------------------------------------------------------ From: CQ Tang <cq.tang@xxxxxxxxx> commit fda3bec12d0979aae3f02ee645913d66fbc8a26e upstream. This is a 32-bit register. Apparently harmless on real hardware, but causing justified warnings in simulation.
