[Intel-gfx] [PATCH 11/20] drm/i915: s/tc_port/hpd_pin/ in GEN11_{TC, TBT}_HOTPLUG()

Ville Syrjala ville.syrjala at linux.intel.com
Tue Oct 6 14:33:40 UTC 2020


From: Ville Syrjälä <ville.syrjala at linux.intel.com>

Use hpd_pin instead of tc_port in the GEN11_{TC,TBT}_HOTPLUG()
to make it clear what they refer to.
