From e307d62d5faba86622c19dca43883ac37bd8e34a Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Mon, 4 Jul 2016 08:08:33 +0100 Subject: [PATCH] drm/i915: Remove redundant queue_delayed_work() from throttle ioctl 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.
