drm/nvc0/fifo: ignore bits in PFIFO_INTR that aren't set in PFIFO_INTR_EN PFIFO_INTR = 0x40000000 appears to be a normal case on nvc0/nve0 PFIFO, the binary driver appears to completely ignore it in its PFIFO interrupt handler and even masks off the bit (as we do) in PFIFO_INTR_EN at init time. The bits still light up in the hardware sometimes though, so lets just ignore any bits we haven't explicitely requested. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
