[PATCH v2 08/23] drm/i915: Unify the TypeC port notation in debug/error messages

Imre Deak
2019-06-20T14:06:18Z

Unify the TypeC port notation in log messages, so that it matches the
spec. For instance the first ICL TypeC port will read as 'Port C/TC#1'.

v2:
- Format print the name only once. (José)
