drm/i2c: tda998x: report whether we actually handled the IRQ

Browse source

Rather than always reporting that the interrupt was handled, we should
report whether we did handle the interrupt.  Arrange to report IRQ_NONE
for cases where we found nothing to do.

This allows us to (eventually) recover from stuck-IRQ problems, rather
than causing the kernel to solidly lock up.
