From a74d782c74644b2e50b3db61e115831cdc3e9010 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Sat, 28 Jun 2014 02:04:09 +0300 Subject: [PATCH] drm/i915: Kill intel_reset_dpio() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Both VLV and CHV handle the cmnreset stuff in the power well code now, so intel_reset_dpio() is no longer needed.
