Subject: [PATCH 4/5] drm/i915: Make more use of the shared engine irq setup
Date: Fri,  1 Jul 2016 17:47:14 +0100	[thread overview]
Message-ID: <1467391635-9902-4-git-send-email-tvrtko.ursulin@linux.intel.com> (raw)
In-Reply-To: <1467391635-9902-1-git-send-email-tvrtko.ursulin@linux.intel.com>

From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>

Use it for legacy engine initialization by adding a
intel_ring_default_irqs helper used by individual engines.
