Re: [PATCH] kconfig: fix allmodconfig

Stephen, All,

Please, test this patch to fix the allmodconfig issue reported by
Stephen.

>From my little testing (some randconfig followed by silentoldconfig, as
well as allmodconfig), this patch seems to fix the issue without any
regression I could ientify.

But since this is sensitive code, I'd like some feedback before this
gets applied.

Thank you!

Regards,
Yann E. MORIN.
