That wouldn't be needed. AFAIK there are _no_ problems if SERIO=y, the
select you suggest is already implemented the other way round.

If SERIO is always y if !EMBEDDED || X86 my patch wouldn't be needed.

Considering this, it seems the patch below is both the best and the
simplest solution for most users.

It doesn't obsolete the other patch since SERIO=m is still possible, but
makes it more unlikely to accidentially set SERIO=m (or even SERIO=n).
