[PATCH 3.11 188/233] drm/radeon: fix DAC interrupt handling on DCE5+

From: Luis Henriques
Date: Fri Feb 07 2014 - 06:52:20 EST


3.11.10.4 -stable review patch. If anyone has any objections, please let me know.

------------------

From: Alex Deucher <alexander.deucher@xxxxxxx>

commit e9a321c6b2ac954a7dbf235f419c255a424a1273 upstream.

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