Line numbers in a source file usually aren't very useful.  They're 
different in every version of the kernel.  Instead just mention which 
functions you're talking about.  It looks like 
authorized_default_show() and authorized_default_store().

Yes, it's true that usb_bus (which is a pointer, not a structure) can
never be NULL.
