Subject: [PATCH 17/27] drm/i915/gem: Rework error handling in default_engines
Date: Mon, 3 May 2021 10:57:38 -0500 [thread overview]
Message-ID: <20210503155748.1961781-18-jason@jlekstrand.net> (raw)
In-Reply-To: <20210503155748.1961781-1-jason@jlekstrand.net>
Since free_engines works for partially constructed engine sets, we can
use the usual goto pattern.
