The comment above the only caller says:
/*
* If Thunderbolt is present, the external DP port is not fully
* switchable. Force its AUX channel to the discrete GPU.
*/
gmux_data->external_switchable =
!bus_for_each_dev(&pci_bus_type, NULL, NULL, is_thunderbolt);
So IHMO keeping the name as is is fine.
