Hi Greg,

After merging the tty tree, today's linux-next build (x86_64 allmodconfig)
failed like this:

.config:4300:warning: symbol value '' invalid for SERIAL_SH_SCI_NR_UARTS
*
* Restart config...
*
*
* Serial drivers
*
8250/16550 and compatible serial support (SERIAL_8250) [M/y/?] m
	.
	.
	.
SuperH SCI(F) serial port support (SERIAL_SH_SCI) [M/n/y] m
  Maximum number of SCI(F) serial ports (SERIAL_SH_SCI_NR_UARTS) [] (NEW) aborted!

Console input/output is redirected. Run 'make oldconfig' to update configuration.


Caused by commit

  f6731485a519 ("tty: serial: sh-sci: Hide number of ports config question")

I have used the tty tree from next-20171215 for today.
