[PATCH V2] usb: xhci_suspend is not stopping the root hub timer for the shared HCD

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

 



V2 - Restart polling (which will restart the timer) for the shared
HCD in xhci_resume().

xhci_suspend() will stop the primary HCD's root hub timer, but leaves
the shared HCD's timer running. This change adds stopping of the
shared HCD timer.
