Subject: usb: hub: Revise wLength for 'get port status' request
X-Git-Url: http://git.dujemihanovic.xyz/img/sics.gif?a=commitdiff_plain;h=53771a490e05e8be750a6ee50002e30df4776e9b;p=u-boot.git

usb: hub: Revise wLength for 'get port status' request

For accuracy, we should use 'sizeof(struct usb_port_status)' as the
wLength for 'get port status' request, although it happens to be
equal to 'sizeof(struct usb_hub_status)'.
