Subject: [PATCH 19/24] drm/radeon: make forcing ring activity a common function
Date: Wed, 25 Apr 2012 15:03:24 -0400	[thread overview]
Message-ID: <1335380609-5804-20-git-send-email-j.glisse@gmail.com> (raw)
In-Reply-To: <1335380609-5804-1-git-send-email-j.glisse@gmail.com>

From: Christian König <deathsimple@vodafone.de>

Nothing chipset or ring specific with it,
so also move it to radon_ring.
