[ 09/15] staging: usbip: changed function return type to void

[Greg Kroah-Hartman]

3.0-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Bart Westgeest <bart@xxxxxxxxxx>

commit ac2b41acfa3efe4650102067a99251587a806d70 upstream.

The function usbip_pad_iso never returns anything but 0 (success).
