    Subject[PATCH] 2.4.17-pre7: fdomain_16x0_release undeclared
    Hello, Alan and all!

    File drivers/scsi/fdomain.h declares a data structure FDOMAIN_16X0 using
    an undeclared function fdomain_16x0_release() in Linux 2.4.17-pre7.

    This is not a problem for the kernel itself, but it breaks compilation of
    pcmcia-cs-3.1.30 because the later uses structure FDOMAIN_16X0.

    The fix is trivial - declare fdomain_16x0_release() the same way as other
    non-static functions from fdomain.c.

    Another partly related problem is a warning in fdomain.c:

    fdomain.c: In function `fdomain_16x0_release':
    fdomain.c:2045: warning: control reaches end of non-void function

    I wonder if the patches that introduce warnings should be allowed in the
    stable branch? Anyway, comparing with other SCSI drivers I see that 0
    should be returned and scsi_unregister(shpnt) should be called before

    Here's the patch. The part for fdomain.h is 100% safe and should be
    applied ASAP. The part for fdomain.c should be safe too but I'll
    appreciate if somebody tests it on a real Future Domain controller.
