Alan Stern 61e8b858ab EHCI: fix remote wakeup regression in 2.6.21-rc
There is one significant difference between the behavior of root hubs
(as embodied in host controller hardware) and external hubs: When a
remote-wakeup signal is received, an external hub sends an interrupt
message at the _end_ of the resume sequence but a root hub generates
and interrupt at the _beginning_ of the resume sequence.  The host
system must poll for the end of the sequence.

When ehci-hcd was converted to interrupt-driven operation instead of
using polling, the remaining need for this particular poll was
overlooked.  This patch (as894) fixes the problem.
