Subject: [PATCH 001/001] USB: ftdi_sio: fix endianess of max packet size

From: Michael Wileczka <mikewileczka@...oo.com>

The USB max packet size (always little-endian) was not being byte swapped on big-endian systems.
Created with 2.6.32.16
Applicable since [USB: ftdi_sio: fix hi-speed device packet size calculation] approx 2.6.31
