USB: ohci-at91 refcount fix for irq wake enables
The attached patch fixes the unbalanced calls to enable_irq_wake() and
disable_irq_wake() in the AT91 USB Host driver.
It should resolve these kernel messages:
Unbalanced IRQ x wake disable
BUG: warning at kernel/irq/manage.c:167/set_irq_wake()
(The original code was debugged before a bug in the genirq wakeup irq
logic was fixed by adding the IRQ wake enable/disable refcounting.
Not all code yet uses the bugfixed model.)
