From: Ville Syrjälä Date: Tue, 12 Jul 2016 12:59:35 +0000 (+0300) Subject: drm/i915: Simplify intel_ddi_get_encoder_port() X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=5a5d24dca44f7c946cbe0d638db81ad58f12e63e;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git drm/i915: Simplify intel_ddi_get_encoder_port() We no longer have any need to look up the intel_digital_port based on the passed in intel_encoder, but we still want to look up the port. Let's just move that logic into intel_ddi_get_encoder_port() and drop the dig_port stuff.
