Not sure what's going on, maybe double-check it's all right. Not sure what happened, one of the patch fragments only has one '@' instead of two, with that fixed the patch applies. Unfortunately the manual application missed some fragments: drivers/gpu/drm/i915/intel_display.c:5350:51: warning: implicit conversion from enumeration type 'enum transcoder' to different enumeration type 'enum pipe' [-Wenum-conversion] intel_set_pch_fifo_underrun_reporting(dev_priv, TRANSCODER_A, ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ^~~~~~~~~~~~ drivers/gpu/drm/i915/intel_display.c:5436:51: warning: implicit conversion from enumeration type 'enum transcoder' to different enumeration type 'enum pipe' [-Wenum-conversion] intel_set_pch_fifo_underrun_reporting(dev_priv, TRANSCODER_A, ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ^~~~~~~~~~~~ drivers/gpu/drm/i915/intel_display.c:5534:51: warning: implicit conversion from enumeration type 'enum transcoder' to different enumeration type 'enum pipe' [-Wenum-conversion] intel_set_pch_fifo_underrun_reporting(dev_priv, TRANSCODER_A, ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ^~~~~~~~~~~~ drivers/gpu/drm/i915/intel_display.c:5563:51: warning: implicit conversion from enumeration type 'enum transcoder' to different enumeration type 'enum pipe' [-Wenum-conversion] intel_set_pch_fifo_underrun_reporting(dev_priv, TRANSCODER_A, What would be the best way forward from here? Revert the manual application and apply again, or a fixup patch?

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.
