[PATCH] USB: UHCI: don't track suspended ports
Someone recently posted a bug report where it turned out that uhci-hcd
was disagreeing with the UHCI controller over whether or not a port was
suspended: The driver thought it wasn't and the hardware thought it was.
This patch (as665) fixes the problem and simplifies the driver by
removing the internal state-tracking completely. Now the driver just
asks the hardware whether a port is suspended.
