Thanks for telling. I'm new to lkml and still learning about the format.

I'm sorry for my hurrying. I ran ``make tools/usb`` with no warning or error,
so I sent this patch. Now it turns out ``make tools/usb`` doesn't cover
tools/usb/usbip. I tried again with ``./autogen.sh && ./configure && make``
and it indeed failed. Since usbip.c doesn't have any reference to
include/linux/compiler.h, it cannot use ``fallthrough``. Thanks again for
pointing out this error.

Thanks,
