2.5.21 -- aty128fb.c: aty128fb.c:1775: `con' undeclared

        I'll throw one in too:

make[2]: Entering directory `/usr/src/linux-2.5.20/drivers/video'

aty128fb.c:1775: (Each undeclared identifier is reported only once
aty128fb.c:1775: for each function it appears in.)
aty128fb.c:1776: incompatible type for argument 1 of `fb_alloc_cmap'
aty128fb.c:1662: warning: `size' might be used uninitialized in this function
make[2]: *** [aty128fb.o] Error 1
make[2]: Leaving directory `/usr/src/linux-2.5.20/drivers/video'
make[1]: *** [_subdir_video] Error 2
make[1]: Leaving directory `/usr/src/linux-2.5.20/drivers'
make: *** [drivers] Error 2

        lines 1775-1776 are:

    size = (fb_display[con].var.bits_per_pixel <= 8) ? 256 : 32;
    fb_alloc_cmap(info->fb_info.cmap, size, 0);

        fb_display[] seems to be the culprit. It's an array, in which has the
'con' field, which is of type int. In all other functions where this array is
used, 'con' is passed to the function as type int. It seems to be missing for
this one.

        Backing out of the change seems to work, as this was added in the
2.5.21 patch, but I'd rather like to know what the proper solution is..

                                                        BL.
