Help text

Say Y here if you want a NULL TTY which simply discards messages.

This is useful to allow userspace applications which expect a console device to work without modifications even when no console is available or desired.

In order to use this driver, you should redirect the console to this TTY, or boot the kernel with console=ttynull.

If unsure, say N.
