<pre>commit 9e267d286af5c5a67995128df40ca3d1f93277a6 (HEAD -> drm-intel-next-queued,
drm-intel/for-linux-next, drm-intel/drm-intel-next-queued)
Author: Chris Wilson <<a href="mailto:chris@chris-wilson.co.uk">chris@chris-wilson.co.uk</a>>

drm/i915/userptr: Fix error handling of mutex_lock_killable()
mutex_lock_killable() returns -EINTR on failure, not the anticipate bool
return like trylock. (Oh no, not again.)
Fixes: 484d9a844d0d ("drm/i915/userptr: Avoid struct_mutex recursion for
mmu_invalidate_range_start")
