Alan Stern f96fba0dbf USB: EHCI: improve handling of the ehci->iaa_in_progress flag 
This patch improves the way ehci-hcd handles the iaa_in_progress flag.
The current code is somewhat careless in this regard:

	The flag is meaningless when the root hub isn't running, most
	particularly after the root hub has been suspended.  But in
	start_iaa_cycle(), the driver checks the flag before checking
	the root hub's state.  They should be checked in the opposite
	order.

	That routine also sets the flag too early, before it has
	definitely committed to starting an IAA cycle.

	The flag is turned off in end_unlink_async().  Upcoming
	changes will call that routine at other times, not just at the
	end of an IAA cycle.  The two actions are logically separate
	(although related), so we separate out a new routine to be
	called in place of end_unlink_async() whenever an IAA cycle
	ends: end_iaa_cycle().

	iaa_in_progress should be turned off when the root hub is
	suspended -- we certainly don't want it still to be set when
	the root hub resumes.  Therefore the call to
	end_unlink_async() in ehci_bus_suspend() should also be
	replaced with a call to end_iaa_cycle().
