From: Matthias Kaehlcke Date: Mon, 17 Jul 2017 18:14:03 +0000 (-0700) Subject: drm/i915: Consistently use enum pipe for PCH transcoders X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a21960339c8c;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git drm/i915: Consistently use enum pipe for PCH transcoders The current code uses in some instances enum transcoder for PCH transcoders and enum pipe in others. This is error prone and clang raises warnings like this: drivers/gpu/drm/i915/intel_dp.c:3546:51: warning: implicit conversion from enumeration type 'enum pipe' to different enumeration type 'enum transcoder' [-Wenum-conversion] intel_set_pch_fifo_underrun_reporting(dev_priv, PIPE_A, false); Consistently use the type enum pipe for PCH transcoders.
