Subject: drm/i915/icl: use combophy/TC helper functions during display detection
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=c0aa834404b33804b3af0822ebcd9881fa8cb214;p=linux.git

drm/i915/icl: use combophy/TC helper functions during display detection

Instead of directly comparing HPD pins use intel_port_is_combophy/tc
helper functions to distinguish between combophy/TC ports.
