[PATCH] USB: DL100B webmail notifier: initialize return value

[PATCH] USB: DL100B webmail notifier: initialize return value

[Melchior FRANZ]

From: Melchior FRANZ <mfranz@aon.at>

If case of an unknown usb_device_id->driver_info (which could only
occur if the info got corrupted somewhere outside the usbled driver),
a debug message depended on an uninitialized value. This was harmless,
but ugly, and gets fixed with this patch.

@Greg:
Argh ... sorry about that. The build system didn't warn me, not even
with EXTRA_CFLAGS=-W. And cppcheck ignored the problem as well. This
must be a plot to damage my reputation!  :-}
