Ah, I guess this would work too. I didn't consider it because SERIO is
a user-visible symbol and we generally try not to 'select' them but instead
use 'depends on.
However, SERIO is already used with 'select' all over the place, so adding
another select is actually safer than adding a dependency (which could
cause dependency loops here).
Actually the best solution is probably to have 'select SERIO' in RMI4, like
config RMI4_F03_SERIO
tristate
depends on RMI4_CORE
depends on RMI4_F03
default RMI4_CORE
select SERIO
As that avoids the 'depends on SERIO=y || RMI4_CORE=SERIO' statement that
is different from the other SERIO users, it keeps it all in one place,
and it doesn't
prevent you from seeing the RMI4_F03 symbol when SERIO=m.
