From: Jesse Barnes Date: Thu, 7 Oct 2010 23:01:07 +0000 (-0700) Subject: drm/i915/dp: remove redundant is_pch_edp checks X-Git-Tag: v2.6.37-rc1~92^2~11^2~60 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=4d9264615b98fe8015eca7d84a9862b1489c69d4;p=karo-tx-linux.git drm/i915/dp: remove redundant is_pch_edp checks If is_edp is true, is_pch_edp will always be true. So limit the calls to the latter function to places where the distinction actually matters.
