Subject: staging: ozwpan: fix access byteorder for wMaxPacketSize in ozhcd.c
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=cb560c401bf2f212167fdf3bfb15e57a78e2fa03;p=linux-beck.git

staging: ozwpan: fix access byteorder for wMaxPacketSize in ozhcd.c

This patch fixes the access byteorder of wMaxPacketSize
which is __le16, following the USB standard, and needs to
be converted into native cpu byteorder in order to be accessed.

Instead of using le16_to_cpu(hep->desc.wMaxPacketSize),
it was used the usb_endpoint_maxp() function, defined in
<uapi/linux/usb/ch9.h>
