From b9fec1672c671fb9f1f44efaaebececcaca57a0e Mon Sep 17 00:00:00 2001 From: Imre Deak Date: Wed, 18 Nov 2015 15:57:25 +0200 Subject: [PATCH] drm/i915: add MISSING_CASE to a few port/aux power domain helpers MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit MISSING_CASE() would have been useful to track down a recent problem in intel_display_port_aux_power_domain(), so add it there and a few related helpers. This was also suggested by Ville in his review of the latest DMC/DC changes, we forgot to address that.
