patch: poulsbo sub driver selects INPUT

Yes, we can fix it by the one-line patch attached.

But IMO, the real problem is that poulsbo stub driver should not select ACPI video driver at all, because there is no dependency between these two drivers.

Comment 2 Randy Dunlap 2010-11-19 00:04:37 UTC 
Yes, the build is fixed by the patch attachment above.

Unfortunately, I was trying to build a kernel with CONFIG_INPUT disabled,
and this STUB driver now makes that impossible, but I suppose that's a different problem.

This one can be closed.
