From 61f3e7704897188d85e5698980316f2929a7c753 Mon Sep 17 00:00:00 2001 From: Rodrigo Vivi Date: Mon, 10 Jul 2017 13:58:52 -0700 Subject: [PATCH] drm/i915/cnl: Add missing type case. Paulo had noticed that inside cnl_ddi_vswing_program the case was handling voltage but with no indication of type where a missing type could also take us to that path. So my first attempt was to add a message to let clear who trigger that path. However DK had a better idea that is to handle the missed type sooner before it might take to that path. So this v2 here uses his approach. v2: Handle missed type sooner.
