Make two patches: - A single patch that adds PCI_VENDOR_ID_THALES to pci_ids.h and also adds a use of it in the MHI driver. - A single patch that adds PCI_VENDOR_ID_QUECTEL to pci_ids.h and also adds a use of it in the MHI driver. That way there's no possibility of build error and no need to coordinate patches.
