From 4d9264615b98fe8015eca7d84a9862b1489c69d4 Mon Sep 17 00:00:00 2001 From: Jesse Barnes Date: Thu, 7 Oct 2010 16:01:07 -0700 Subject: [PATCH] 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.
