undefined "pm3fb_setup()"

undefined "pm3fb_setup()"

[Robert P. J. Day]

  i'm guessing someone's already spotted this but, with "make
allyesconfig" on x86:

...
  LD      .tmp_vmlinux1
drivers/built-in.o: In function `pm3fb_init':
drivers/video/pm3fb.c:977: undefined reference to `pm3fb_setup'
...

  the reason seems to be this excerpt from drivers/video/pm3fb.c:

================================================================
int __init pm3fb_init(void)
{
        /*
         *  For kernel boot options (in 'video=pm3fb:<options>' format)
         */
#ifndef MODULE                       <-----------------------
        char *option = NULL;

        if (fb_get_options("pm3fb", &option))
                return -ENODEV;
        pm3fb_setup(option);
#endif

        return pci_register_driver(&pm3fb_driver);
}

static void __exit pm3fb_exit(void)
{
        pci_unregister_driver(&pm3fb_driver);
}

#ifdef MODULE                        <------------------------
        /*
         *  Setup
         */

/*
 * Only necessary if your driver takes special options,
 * otherwise we fall back on the generic fb_setup().
 */
int __init pm3fb_setup(char *options)
{
        /* Parse user speficied options (`video=pm3fb:') */
        return 0;
}
#endif /* MODULE */
=================================================================

  so the call to pm3fb_setup() is included if MODULE is *not* defined,
but the actual code for that routine is included if MODULE *is*
defined.  unless i've misread something.

I've spotted this before, but forgotten about it.  Yes, the above should
be #ifndef

Already sent Linus and akpm a patch. 

Thanks.
