From: Geert Uytterhoeven on
commits 638157bc1461f6718eeca06bedd9a09cf1f35c36 ("serial167: prepare to push
BKL down into drivers") and 4165fe4ef7305609a96c7f248cefb9c414d0ede5 ("tty:
Fix up char drivers request_room usage") removed code without removing the
corresponding variables:

| drivers/char/serial167.c: In function 'cd2401_rx_interrupt':
| drivers/char/serial167.c:630: warning: unused variable 'len'
| drivers/char/serial167.c: In function 'cy_ioctl':
| drivers/char/serial167.c:1531: warning: unused variable 'val'

Remove the variables to kill the warnings.

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
