Possible bug in kbuild

A problem with configuration of IWLWIFI has been bisected to commit 48e2934, where a new section was added to drivers/net/wireless/iwlwifi/Kconfig with the following code:

# don't call it _MODULE -- will confuse Kconfig/fixdep/...
config IWLWIFI_OPMODE_MODULAR
bool
default y if IWLDVM=m
default y if IWLMVM=m

When the above section is present, 'make xconfig' fails to show a "Debugging options" menu' even though 'make menuconfig' displays correctly. despite the incorrect on-screen display, xconfig does not delete the affected info in .config after it was set by menuconfig, thus the bug only seems to affect the display in xconfig.

Is there anything wrong with that section in iwlwifi's Kconfig, or is it a bug in xconfig?

Thanks,

Larry
