From 844b2f9a5d061e5d2d09b0664fad0e0bfa39dc39 Mon Sep 17 00:00:00 2001 From: Ander Conselvan de Oliveira Date: Wed, 27 Apr 2016 15:44:18 +0300 Subject: [PATCH] drm/i915: Unduplicate chv_data_lane_soft_reset() The function chv_data_lane_soft_reset() was duplicated in DP and HDMI code. Move it to intel_dpio_phy.c.
