[Intel-gfx] [PATCH 4/5] drm/i915: Simplify the uncleared FIFO underrun detection

From: Ville Syrjälä ville.syrj...@linux.intel.com Checking whether the error interrupt was enabled or not isn't really necessary when we check for uncleared FIFO underruns. If it was enabled we'll race with the interrupt handler a bit, but that seems OK as we still claim the interrupt.
