[PATCH 2.5] Minor fix for driver/serial/core.c

[Jean Tourrilhes]

	Hi Russell,

	The following command will do nothing at all on 2.5.X :
		setserial /dev/ttyS0 uart none

	I sent you the bug fix for that a few months ago, but as
2.5.67 this trivial bug is still not fixed. The patch is below...

	Have fun...

	Jean
