Generally speaking, sure.  But why remove just this one?  Is it
because it loosely follows a
pattern that was deemed removable in that slidedeck you linked to?
(the "usb_submit_urb()" part)?

Yes, I wrote that code, and in case this driver doesn't load, I'd like
to know precisely where
initialization failed.  I can happily spare a few bytes for that.
