No, this is not even a warning.

When Kconfig parsess a 'depends on' line, if the symbol does not exist
yet, it is added to the list of symbols, in case it is defined later on.

But then there is no way to know if a symbol was added because there was
a corresponding 'config' (or 'menuconfig' or 'choice') entry in any of
the Config.in files, or because it was added due to it being listed in a
'depends on' (or a 'select').

We can't even rely on the symbol having no type, since it is valid for a
symbol to have no type (can't recall off-the-top-of-my-head what case it
was, but it is valid in the Kconfig grammar).

Regards,
Yann E. MORIN.
