rc_interrupt also needs to protect data with locks (on UP it was ok,
because interrupts were disabled).
Around line 1130 there are two msleep_interruptible calls under lock
(this was wrong before too).
Some functions don't need to save flags, because you know they are
never called from interrupt (all from riscom_ops?).
IMHO it would be nice to notice somewhere what is protected by lock
(rc_board and rc_port structures); and it would probably be better to
have a lock per board in riscom_board struct.
