From: Eugeni Dodonov Date: Fri, 6 Jul 2012 18:42:36 +0000 (-0300) Subject: drm/i915: initialize power wells in modeset_init_hw X-Git-Tag: v3.12-rc1~2248^2~61^2~74 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0232e927f8b0b37f5c82648f9bc45e55fb245068;p=kernel%2Fkernel-generic.git drm/i915: initialize power wells in modeset_init_hw This initializes power wells within the modeset_init_hw routine. Testing has shown that this works for both driver load time and for suspend-resume code paths.
