I think the call of dgap_cleanup_tty()
in dgap_cleanup_module() from dgap_init_module() is not reached.
Because dgap_init_module() is called when driver is loaded, at this
point of time,
there are no boards that are initialized.(dgap_numboards is zero)

And the change log of this is needed to modify for clearing message.

Thanks.
