From 6d729bff304f3b81062e21cd333a639fda4244b3 Mon Sep 17 00:00:00 2001 From: Paulo Zanoni Date: Tue, 7 Oct 2014 16:11:11 -0300 Subject: [PATCH] drm/i915: only run hsw_power_well_post_enable when really needed MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Only run it after we actually enable the power well. When we're booting the machine there are cases where we run hsw_power_well_post_enable without really needing, and even though this is not causing any real bugs, it is unneeded and causes confusion to people debugging interrupts.
