Various drivers in the kernel use `is_thunderbolt` or `pci_is_thunderbolt_attached` to designate behaving differently from a device that is internally in the machine. This relies upon checks for a specific capability only set on Intel controllers.
Non-Intel USB4 designs should also match this designation so that they can be treated the same regardless of the host they're connected to.
As part of adding the generic USB4 controller code, it was realized that `is_thunderbolt` and `pcie_is_thunderbolt_attached` have been overloaded.
Instead migrate to using removable attribute from device core.
Changes from v1->v2: - Add Alex's tag to first patch - Move lack of command completion into a quirk (Lukas) - Drop `is_thunderbolt` attribute and `pci_is_thunderbolt_attached` and use device core removable attribute instead - Adjust all consumers of old attribute to use removable
Mario Limonciello (9): thunderbolt: move definition of PCI_CLASS_SERIAL_USB_USB4 PCI: Move `is_thunderbolt` check for lack of command completed to a quirk PCI: drop `is_thunderbolt` attribute PCI: mark USB4 devices as removable drm/amd: drop the use of `pci_is_thunderbolt_attached` drm/nouveau: drop the use of `pci_is_thunderbolt_attached` drm/radeon: drop the use of `pci_is_thunderbolt_attached` platform/x86: amd-gmux: drop the use of `pci_is_thunderbolt_attached` PCI: drop `pci_is_thunderbolt_attached`
