Revert "drm/i915: Fix mutex->owner inspection race under DEBUG_MUTEXES"
The core fix was applied in
commit a63b03e2d2477586440741677ecac45bcf28d7b1
Author: Chris Wilson <chris@chris-wilson.co.uk>
Date: Tue Jan 6 10:29:35 2015 +0000
mutex: Always clear owner field upon mutex_unlock()
(note the absence of stable@ tag)
so we can now revert our band-aid commit 226e5ae9e5f910 for -next.
