From 641a969eff3ffb01088736ef9531caffe38a6fd9 Mon Sep 17 00:00:00 2001 From: Jani Nikula Date: Thu, 28 May 2015 15:43:49 +0300 Subject: [PATCH] drm/i915: simplify conditions for skipping the 2nd hpd loop iterations Multiple positive and negative checks for hpd[i] & hotplug_trigger gets hard to read. Simplify. This should make follow-up patches merging the two loops easier. No functional changes.
