Subject: [PATCH 11/25] drm/i915/request: Remove the hook from await_execution
Date: Thu, 29 Apr 2021 14:03:26 -0500	[thread overview]
Message-ID: <20210429190340.1555632-12-jason@jlekstrand.net> (raw)
In-Reply-To: <20210429190340.1555632-1-jason@jlekstrand.net>

This was only ever used for FENCE_SUBMIT automatic engine selection
which was removed in the previous commit.
