tty: USB: serial/mct_u232, fix tty refcnt
Stanse found a tty refcnt leak in read_int_callback. In fact it's handled wrong altogether. tty_port_tty_get can return NULL and it's not checked in that manner. Fix that by checking the tty_port_tty_get retval and put tty kref properly. http://stanse.fi.muni.cz/ Signed-off-by: Jiri Slaby <jirislaby@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
