Subject: [PATCH 1/3] drm/i915: rename macro parameter(ring) to (engine)
Date: Wed, 20 Jul 2016 18:16:05 +0100	[thread overview]
Message-ID: <1469034967-15840-2-git-send-email-david.s.gordon@intel.com> (raw)
In-Reply-To: <1469034967-15840-1-git-send-email-david.s.gordon@intel.com>

'ring' is an old deprecated term for a GPU engine. Here we make the
terminology more consistent by renaming the 'ring' parameter of lots of
macros that calculate addresses within the MMIO space of an engine.
