[PATCH] usb: host: xhci: move HC_STATE_SUSPENDED check to xhci_suspend()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



that check will have to be done by all users
of xhci_suspend() so it sounds a lot better to
move the check to xhci_suspend() in order to
avoid code duplication.
