Subject: drm/radeon: fix DAC interrupt handling on DCE5+
X-Git-Tag: submit/tizen_common/20140905.094502~782
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=7d63ec0a46c7c81cf97ba9b4855763e69a6ff16e;p=sdk%2Femulator%2Femulator-kernel.git

drm/radeon: fix DAC interrupt handling on DCE5+

commit e9a321c6b2ac954a7dbf235f419c255a424a1273 upstream.

DCE5 and newer hardware only has 1 DAC.  Use the correct
offset.  This may fix display problems on certain board
configurations.
