X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=d1ab903d2552b2362339b19203c7f01c797cb316;p=openwrt%2Fstaging%2Fblogic.git

USB: ftdi_sio: fix endianess of max packet size

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
