From 6a712a20bff467e82c3507c4286f04499af1c52d Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Mon, 14 Jan 2019 14:21:20 +0000 Subject: [PATCH] drm/i915/hotplug: Track temporary rpm wakeref Keep track of the temporary rpm wakeref inside hotplug detection, so that we can cancel it immediately upon release and so clearly identify leaks.
