From: Alex Deucher Date: Thu, 18 Sep 2014 20:36:08 +0000 (-0400) Subject: drm/radeon: consolidate r600_audio.c into r600_hdmi.c X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=721566768787f3b4790d22d993d70befdd440f64;p=openwrt%2Fstaging%2Fblogic.git drm/radeon: consolidate r600_audio.c into r600_hdmi.c Most of that functionality is only used by r600_hdmi.c and I'm planning to change that further.
