Well, it's not up to serialio.h to include things for serialio.c. That
however makes me realize that the culprit is actually
f79b0d9 (which actually doesn't make much sense since linux/serial.h is
getting included a couple of lines above...).

I don't know what this "use <linux/serial.h> instead <asm/serial.h>"
warning is about, but *no* header in include/ includes asm/serial.h, so
there is no way to get the SERIAL_PORT_DFNS definition just by including
linux/serial.h, we really need asm/serial.h, just like 8250*.c do.

So we really need serialio.c to include linux/serial_core.h then
asm/serial.h, as my patch does.
