Subject: usb: hub: Fix usb_get_port_status() for big-endian platforms
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=c1125bad6cda95b45ec151e6d2227fb2b7b03a43;p=u-boot.git

usb: hub: Fix usb_get_port_status() for big-endian platforms

Add missing endianness conversions to usb_get_port_status(). This
(amongst others) is necessary to enable the use of USB 3 hubs on
big-endian platforms like MIPS Octeon.
