    SubjectRe: [PATCH] MPT: make all Fusion MPT sub-choices singly selectable

    based on randy's earlier email, here's an updated model for a patch
    that adds a couple selectors to the Device Drivers menu, one for a
    boolean MPT, and the other for a tristate MTD. it *seems* to work.
    (one improvement that *could* be made would be to also edit the MTD
    sub-Kconfig files and remove their "depends on MTD" clauses since they
    wouldn't be necessary anymore. but it might be safer to leave those
    alone just in case someone decides to source those files from
    elsewhere some day.)

    again ... thoughts?
