[Intel-gfx] [PATCH 035/190] drm/i915: Remove redundant queue_delayed_work() from throttle ioctl

[Chris Wilson]

We know, by design, that whilst the GPU is active (and thus we are
throttling) the retire_worker is queued. Therefore attempting to requeue
it with queue_delayed_work() is a no-op and we can safely remove it.
