i915: suspend/resume interrupt state
In the KMS case, enter/leavevt won't fix up the interrupt handler for us, so we need to do it at suspend/resume time. Make sure we don't fail the resume if the chip is hung either. Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
