USB: ftdi_sio: fix endianess of max packet size
commit d1ab903d2552b2362339b19203c7f01c797cb316 upstream. The USB max packet size (always little-endian) was not being byte swapped on big-endian systems. Applicable since [USB: ftdi_sio: fix hi-speed device packet size calculation] approx 2.6.31 Signed-off-by: Michael Wileczka <mikewileczka@yahoo.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
