Subject: [PATCH] drm/i915: Optimize pipe irq handling on bdw
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

We have a per-pipe bit in the master irq control register, so use it.
This allows us to drop the masks for aggregate interrupt bits and be a
bit more explicit in the code. It also removes one indentation level.
