Subject: [PATCH 25/27] drm/radeon: make forcing ring activity a common function
Date: Tue,  1 May 2012 13:19:35 -0400	[thread overview]
Message-ID: <1335892777-7357-26-git-send-email-j.glisse@gmail.com> (raw)
In-Reply-To: <1335892777-7357-1-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.
