USB: serial/keyspan_pda, fix potential tty NULL dereferences Make sure that we check the return value of tty_port_tty_get. Sometimes it may return NULL and we later dereference that. There are several places to check. For easier handling, tty_port_tty_get is moved directly to the palce where needed in keyspan_pda_rx_interrupt.
