rt2x00: Sequence counter should be protected in irqsave
The sequence counter can be accessed in IRQ context, which means the lock protecting the counter should be irqsave. To prevent making the entire intf->lock irqsave without reason, create a new lock which only protects the sequence counter. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.
