[Intel-gfx] [PATCH 06/11] drm/i915/dp: Add link training debug and error printing helpers

Imre Deak
2023-04-26T16:53:36Z

Add functions for printing link training debug and error messages, both
to prepare for the next patch, which downgrades an error to debug if the
sink is disconnected and to remove some code duplication.
