misc: pti, fix tty_port count
We now have *one* tty_port for both TTYs. How this was supposed to work? Change it to have a tty_port for each of TTYs. Signed-off-by: Jiri Slaby <jslaby@suse.cz> Cc: J Freyensee <james_p_freyensee@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
