Kconfig troubles when using menuconfig - Was: [patch]Re: linux-2.6.22-rc5-gf1518a0 build #300 failed in zc0301_core.c

Hi Roman,

Several instabilities on Kconfig started to happen after replacing
Kconfig menus to use menuconfig, as this one, reported by Oliver:

In this specific case, all V4L USB drivers depends on V4L_USB_DRIVERS,
that depends, in turn, on USB. So, if USB is not selected,
V4L_USB_DRIVERS should be unselected, unselecting zc0301.

Unfortunately, the Kernel building system is not properly handling it.

This is the (snipped) media/video/Kconfig:

menuconfig V4L_USB_DRIVERS
        bool "V4L USB devices"
        depends on USB
        default y

if V4L_USB_DRIVERS

source "drivers/media/video/pvrusb2/Kconfig"

<snip/>

source "drivers/media/video/zc0301/Kconfig"

<snip/>

endif # V4L_USB_DRIVERS

Cheers,
Mauro
