hi all,

For kernel 2.5.62 I get the following error:

   ld -m elf_i386  -r -o init/built-in.o init/main.o init/version.o 
init/do_mounts.o init/initramfs.o
        ld -m elf_i386 -e stext -T arch/i386/vmlinux.lds.s

vmlinux
drivers/built-in.o: In function `b1pci_pci_remove':
drivers/built-in.o(.text+0x90665): undefined reference to `b1pciv4_remove'

--------

Reason:

The combination 

ISDN_DRV_AVMB1_B1PCI = Y
ISDN_DRV_AVMB1_B1PCIV4 = N

does not seem to work, as ISDN_DRV_AVMB1_B1PCIV4 undefines the static function 
b1pciv4_remove(). 

If those flags need to be set both, why not make one flag instead of two?
