    I haven't seen any rule about it, but nominally the drivers support the
    configurations found in the kernel tree, so if some board physically
    existing and soon-to-run linux hotplugs chips like this, then have it
    __dev{init|exit} else __{init|exit} IMHO.

    Of course you can design for all plausible use cases but it will pile up
    indefinitely. Personally I try to not design software for a hardware until it
    exists, and I like the IETF catch-phrase "rough consensus and running
    code" and this sort of fits that :-)

    Yours,
    Linus Walleij
