[PATCH] Fix NULL pointer dereference in isdn_tty_at_cout
The changes in the tty related code introduced wrong parenthesis in a if
condition in the isdn_tty_at_cout function. This caused access to index -1
in the dev->drv[] array. This patch change it back to the correct
condition from the previous versions.
