zd1211rw: correct use of usb_bulk_msg on interrupt endpoints
zd1211rw is using usb_bulk_msg() with usb_sndbulkpipe() on interrupt endpoint. However usb_bulk_msg() internally corrects this and makes interrupt URB. It's better to change usb_bulk_msgs in zd1211rw to usb_interrupt_msg for less confusion. Signed-off-by: Jussi Kivilinna <jussi.kivilinna@mbnet.fi> Signed-off-by: John W.
