Subject: [PATCH 2/2]drivers/usb/host/ehci-hub.c Fix variable 'i' set but not used

The below fixes a build warning from GCC:

drivers/usb/host/ehci-hub.c: In function 'create_companion_file':
drivers/usb/host/ehci-hub.c:533:6: warning: variable 'i' set but not used

Let me know if these are totally wrong etc.. And I'll try
my best to resend properly..
