Please use a newline every 70-72 characters. Some email clients don't do automatic

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?
in menuconfig or nconfig:
Notice that 'Debugging options' is not indented under iwlwifi, but listed at the
same indent level. That is a huge clue.
in xconfig:
The 'Debugging options' menu is displayed, but it's not where you expect or want
it to be found. Look under 'Wireless LAN' and immediately under 'Atheros Wireless Cards'
and it says 'Debugging options' (on the left panel). Then the debugging options are
displayed in the right hand panel.
This is a common problem. I have made Kconfig patches for it several times.
Here is another one. Works for me.

Fix iwlwifi options so that they all depend on IWLWIFI and are
displayed under the iwlwifi driver instead of in other unexpected
places.

Rabdy,
Sorry about the long lines. I thought Thunderbird was inserting a newline after
72 characters. At least, that is what shows on my screen.
I can report that your fix does take care of the problem for me.
Thanks,
Larry
