I assume that this whole series will be merged in one go through another tree (e.g. the PCI tree), so here is my ack for merging this patch through another tree: Acked-by: Hans de Goede <hdegoede@redhat.com> Regards, Hans > --- > drivers/platform/x86/apple-gmux.c | 2 +- > 1 file changed, 1 insertion(+), 1 deletion(-) > > diff --git a/drivers/platform/x86/apple-gmux.c b/drivers/platform/x86/apple-gmux.c > index 04232fbc7d56..ffac15b9befd 100644 > --- a/drivers/platform/x86/apple-gmux.c > +++ b/drivers/platform/x86/apple-gmux.c > @@ -596,7 +596,7 @@ static int gmux_resume(struct device *dev) > > static int is_thunderbolt(struct device *dev, void *data) > { > - return pci_is_thunderbolt_attached(to_pci_dev(dev)); > + return dev_is_removable(dev); > } > > static int gmux_probe(struct pnp_dev *pnp, const struct pnp_device_id *id) >

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. Regards, Hans

Currently `pci_is_thunderbolt_attached` is used to indicate a device is connected externally. The PCI core now marks such devices as removable and downstream drivers can use this instead.
