The tty count sanity check may need the BKL, that isn't clear. However it is clear that the count use of the lock is internal and independant of the bigger use of the lock. Furthermore the file list locking is also separately locked already Signed-off-by:

moxa_openlock is used for several situations where we want to handle the case of an ioctl that crosses many ports (not just the open tty), and also cases where an open races a deinit (eg a pci unplug) and we hangup a port before we can cope with that. The non open race cases can use the moxa_lock spinlock. This simplifies sorting out the remaining mess. Signed-off-by:

- The open lock is needed to fix up the case of a board reset occuring during tty open but too early for a sane hangup response. - The lock can however got for other cases - Use the port mutex for get/setserial - Fix up the confused lack of locking on the THROTTLE and other bits in the private flags. Just use set/test/clear bit and it covers the cases we need Signed-off-by:

At first this looks a fairly trivial conversion but we can't quite push everything into the right format yet. The open side is easy but care is needed over the setserial methods. Fix up the locking now that we've adopted the port->mutex locking rule for the initialization. Signed-off-by:

Some devices want to set IO_ERROR in their activate methods so that you can be handed a 'dead' port for operations like setserial. Thus we need to clear the flag before activate so that activate can choose to set the flag and still return 0. This is fine as the file handle/tty are not accessible to the user yet. Signed-off-by:
