No need for a private macro. It already exists.
/**
* USB_DEVICE_AND_INTERFACE_INFO - describe a specific usb device with a class of usb interfaces
* @vend: the 16 bit USB Vendor ID
* @prod: the 16 bit USB Product ID
* @cl: bInterfaceClass value
* @sc: bInterfaceSubClass value
* @pr: bInterfaceProtocol value
*
* This macro is used to create a struct usb_device_id that matches a
* specific device with a specific class of interfaces.
*
* This is especially useful when explicitly matching devices that have
* vendor specific bDeviceClass values, but standards-compliant interfaces.
