    We need to keep the -DHAVE_FOO stuff there, in order to satisfy the
    following requirements:

    1) To allow the option of only selecting those frontends required by
    specific dvb hardware, without forcing all modules to be loaded... This
    feature is optional, and I implemented it in response to the demand from
    some hybrid v4l/dvb device users, (and myself) Why force a driver to
    load every frontend module if it isnt required by the hardware? --
    apparantly the implementation was less than perfect. I had originally
    intended for this to live in -mm for a bit, but when the merge window
    came around, Mauro had sent it upstream before I had the chance to
    create alternate patches for linus' tree.

    2) (more importantly) To allow v4l-kernel cvs to retain backwards
    compatability with older kernels..

    I had originally tried to rename these to use the Kconfig variables, but
    LKML people asked for it to be changed back.

    Please do not remove this feature -- if it is broken, then we should try
    to fix it, rather than remove it. If the specific frontend selection
    isn't working, then I guess we can revert back to the old behavior where
    every frontend is forced, but I would rather not.

    If it fixes Gene's problem (a quick glance at his emails suggests that
    it does) then:

    Acked-by: Michael Krufky <>

    although Sam Ravnborg's suggestion looks better to me. Unfortunately, I
    will be unable to test this out on my system until After Thanksgiving
    (on Friday) ...
