Subject: [PATCH 10/21] drm/i915/request: Remove the hook from await_execution
Date: Fri, 23 Apr 2021 17:31:20 -0500 [thread overview]
Message-ID: <20210423223131.879208-11-jason@jlekstrand.net> (raw)
In-Reply-To: <20210423223131.879208-1-jason@jlekstrand.net>
This was only ever used for bonded virtual engine execution. Since
that's no longer allowed, this is dead code.
