Subject: [PATCH 29/62] drm/i915: Rename intel_context[engine].ringbuf
Date: Fri,  3 Jun 2016 17:36:54 +0100	[thread overview]
Message-ID: <1464971847-15809-30-git-send-email-chris@chris-wilson.co.uk> (raw)
In-Reply-To: <1464971847-15809-1-git-send-email-chris@chris-wilson.co.uk>

Perform s/ringbuf/ring/ on the context struct for consistency with the
ring/engine split.
