Subject: [PATCH 11/11] drm/i915: Cleanup after failed initialization of ringbuffers
Date: Thu, 27 May 2010 13:18:22 +0100
Message-ID: <1274962702-6530-12-git-send-email-chris@chris-wilson.co.uk> (raw)
In-Reply-To: <1274962702-6530-1-git-send-email-chris@chris-wilson.co.uk>

The callers expect us to cleanup any partially initialised structures
before reporting the error.
