From 5b6eefd667847ca6bd6925f7bd1afcecc457c889 Mon Sep 17 00:00:00 2001 From: Manasi Navare Date: Wed, 21 Aug 2019 14:59:50 -0700 Subject: drm/i915/dp: Fix DSC enable code to use cpu_transcoder instead of encoder->type This patch fixes the intel_configure_pps_for_dsc_encoder() function to use cpu_transcoder instead of encoder->type to select the correct DSC registers that was wrongly used in the original patch for one DSC register isntance.
