From: Ander Conselvan de Oliveira Date: Wed, 27 Apr 2016 12:44:18 +0000 (+0300) Subject: drm/i915: Unduplicate chv_data_lane_soft_reset() X-Git-Tag: MMI-PSA29.97-13-9~7427^2~45^2~142 X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=844b2f9a5d061e5d2d09b0664fad0e0bfa39dc39;p=GitHub%2FMotorolaMobilityLLC%2Fkernel-slsi.git 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.
