USB: xhci: Re-purpose xhci_quiesce().
xhci_quiesce() is basically a no-op right now. It's only called if HC_IS_RUNNING() is true, and the body of the function consists of a BUG_ON if HC_IS_RUNNING() is false. For the new xHCI watchdog timer, we need a new function that clears the xHCI running bit in the command register, but doesn't wait for the halt status to show up in the status register. Re-purpose xhci_quiesce() to do that. Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
