TTY: tty_alloc_driver() returns error pointers
We changed these from alloc_tty_driver() to tty_alloc_driver() so the error handling needs to modified to check for IS_ERR() instead of NULL. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Acked-by: Jiri Slaby <jslaby@suse.cz> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
