No, they aren't always.
Look for example at the last one in drivers/input/mouse/Kconfig:
config MOUSE_ATARI
tristate "Atari mouse"
depends on ATARI
select ATARI_KBD_CORE
This is perfectly correct (the select'ed symbol is only unavailable when
the dependency can't be fulfilled), and all things to "fix" the warning
will make it worse.
Not sure what you mean here. The select'ed symbol here is unavailable
because not all arch's define it. However, the symbol that selects it is
in drivers/input/... and hence run for all arch's. That's the simple issue
here that is resolved by this fix.
