[PATCH 05/19] drm/i915/selftest: Drop manual request wakerefs around hangcheck

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



We no longer need to manually acquire a wakeref for request emission, so
drop the redundant wakerefs, letting us test our wakeref handling more
precisely.
