In function `ehci_brcm_hub_control`, like following code,
it filters out the case where the upper byte of wIndex is nonzero,
so it need be replaced with temp.
```
if ((typeReq == GetPortStatus) &&
(wIndex && wIndex <= ports) && // need to be replaced
ehci->reset_done[wIndex-1] &&
time_after_eq(jiffies, ehci->reset_done[wIndex-1]) &&
(ehci_readl(ehci, status_reg) & PORT_RESUME)) {
```
