Error in usb_control_msg Documentation

[Chris BeHanna <behanna@zbzoom.net>]

The generated documentation in your Kernel API section contains a
grievous error:  the return values for usb_control_msg() are listed as
negative for error, 0 for success.  This is not correct:  a successful
return for usb_control_msg() will result in a nonnegative integer
indicating the actual number of bytes sent or received in the "data"
parameter.

Please fix this ASAP.  This mistake cost me a lot of time, and I'd hate
to see others hamstrung by it.

Sincerely,
