[PATCH 2/2] USB: ehci_brcm_hub_control: replace wIndex-1 with temp

[Haimin Zhang <tcs.kernel@gmail.com>]

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)) {
```
