Yes, the same error as reported by Fengguang earlier:
http://marc.info/?l=linux-kbuild&m=137214773928335&w=4
And caused by (yet once more):
8357b48: kconfig: fix randomising choice entries in presence of KCONFIG_ALLCONFIG
Basically, the issue is:
- 'Enumeration method' is a tristate choice
- for tristate choices, it is possible to select zero, one or more of the
symbols in the choice
- if no symbol is selected (randomly or otherwise) in a tristate choice,
then the choice symbol itself has no assigned 'value'
- then silentoldconfig whines
It worked so far as a side effect of another bug (which 8357b48 tries to
fix), and now this new one has been exposed.
I have to think in a calm place tonight, when I'm back from work...
This one is starting to drive me crazy, really... :-(

Yann E. MORIN.
