From 21d6e0bde50713922a6520ef84e5fd245b05d468 Mon Sep 17 00:00:00 2001 From: Ander Conselvan de Oliveira Date: Fri, 20 Jan 2017 16:28:43 +0200 Subject: [PATCH] drm/i915: Don't init hpd polling for vlv and chv from runtime_suspend() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit An error in the condition for avoiding the call to intel_hpd_poll_init() for valleyview and cherryview from intel_runtime_suspend() caused it to be called unconditionally. Fix it.
