From: John Harrison <John.C.Harrison@xxxxxxxxx>
Note: i915_trace_irq_get is no longer inline as it requires accessing the
internals of the request structure. As i915_drv.h includes intel_ringbuffer.h,
an inline within the former is never going to be able to use details from the
latter.
For: VIZ-4377
