From: Ander Conselvan de Oliveira Date: Wed, 27 Apr 2016 12:44:24 +0000 (+0300) Subject: drm/i915: Unduplicate pre encoder enabling phy code X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=5f68c275b46460e6c2923763e7842011dabd3585;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git drm/i915: Unduplicate pre encoder enabling phy code The phy code in vlv_pre_enable_dp() and vlv_hdmi_pre_enable() is exectly the same, so extract it to intel_dpio_phy.c.
