Subject: [PATCH 02/13] drm/omapdrm: Use unlocked gem unreferencing
Date: Wed, 30 Mar 2016 11:40:41 +0200	[thread overview]
Message-ID: <1459330852-27668-3-git-send-email-daniel.vetter@ffwll.ch> (raw)
In-Reply-To: <1459330852-27668-1-git-send-email-daniel.vetter@ffwll.ch>

dev->struct_mutex, which these paths don't. Enforcing this requirement
has become a bit more strict with
