Btw, it missed rename as well there. Thanks for spotting this!

There are a lot of examples in the kernel where PCI_VDEVICE() is used and still looks not so convenient due to additional driver_data field attached. Introduce PCI_DEVICE_DATA() macro to fully describe device ID entry in shortest possible form. For example, before: { PCI_VDEVICE(INTEL, PCI_DEVICE_ID_INTEL_MRFLD), (kernel_ulong_t) &dwc3_pci_mrfld_properties, }, after: { PCI_VDEVICE(INTEL, INTEL_MRFLD, &dwc3_pci_mrfld_properties }, Drivers can be converted later on in independent way. While here, remove the unused macro with the same name from Ralink wireless driver.
