[PATCH 23/88] drm/i915: Move the get/put irq locking into the caller
Chris Wilson
chris at chris-wilson.co.uk
Mon Apr 18 22:45:02 UTC 2016
With only a single callsite for intel_engine_cs->irq_get and ->irq_put,
we can reduce the code size by moving the common preamble into the
caller, and we can also eliminate the reference counting.
For completeness, as we are no longer doing reference counting on irq,
rename the get/put vfunctions to enable/disable respectively.
