A 'request_irq()' call is not balanced by a corresponding 'free_irq()' in
the error handling path, as already done in the remove function.
Add it.

I also wonder if the loop above is correct. The 'i < MAX_PORT' looks really
spurious to me.
'tty_port_destroy' can be called twice for the same entry (once before
branching in the error handling path, and once in here) and
'tty_unregister_device'/'tty_port_destroy' will be called on entries
that have not been 'tty_port_init'ed or 'tty_port_register_device'd.
I don't know if it may be an issue.
