[PATCH 4.2 007/120] drm/radeon: fix HDMI quantization_range for pre-DCE5 asics
From: Greg Kroah-Hartman
Date: Sat Sep 19 2015 - 14:11:35 EST
4.2-stable review patch. If anyone has any objections, please let me know.
------------------
From: Alex Deucher <alexander.deucher@xxxxxxx>
commit 86b7709d48f0df8796bddd7e1ce45c6fb7a7c6ec upstream.
Support for output_csc is only available on DCE5 and newer so
don't mess with the HDMI quantization_range on pre-DCE5 asics.
