[PATCH 4/6] Char: mxser_new, don't check tty_unregister retval

[Jiri Slaby]

mxser_new, don't check tty_unregister retval

Like other drivers silently unregister_tty_driver and put_tty_driver. It
shouldn't be busy when module release function is called, since we are not
bsd, no refs shouldn't be held.
