------------------------------------------------------
Subject: USB: don't propagate FREEZE or PRETHAW suspends
From: Alan Stern <stern@xxxxxxxxxxxxxxxxxxx>
This patch (as992) fixes a recently-added bug. During a FREEZE or PRETHAW
suspend notification, non-root devices don't actually get suspended. So we
shouldn't tell their parent hubs that they did.
(This code path used to be skipped over, until the FREEZE/PRETHAW test got
moved out of usb_suspend_both() into generic_suspend().)
