Subject: [PATCH] usbnet: ipheth: Simplify device detection
All Apple products use the same protocol for tethering over USB.
To simplify the code and make it future proof, use
USB_VENDOR_AND_INTERFACE_INFO() instead of
USB_DEVICE_AND_INTERFACE_INFO() to automatically detect and support
all existing and future Apple products using the same interface.
Signed-off-by: Guenter Roeck <linux@...ck-us.net>

Tested with various iPads and iPhones up to X. iPhone 6 and later
up to and including X all use product ID 0x12a8, so this patch is
not strictly required, but it does simplify the code.
