I am assuming this is a stupid question but since I am new I will ask it anyway.
Can the usb_bus structure be Null? If can I will send it a patch removing the
fix mes on lines 854 and 878 of hcd.c .

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.

If that is the case I will send a patch, removing the lines as it
seems we don't need to check for NULL then based
on your information.
