Subject: kconfig: Clarify menu and 'if' dependency propagation
X-Git-Url: https://jxself.org/git/?p=carl9170fw.git;a=commitdiff_plain;h=7b68083e2112e4e729df9378c043fd7a711dcba8

kconfig: Clarify menu and 'if' dependency propagation

It is not obvious that the last two cases refer to menus and ifs,
respectively, in the conditional that sets 'parentdep'.

Automatic submenu creation is done later, so the parent can't be a
symbol here.

No functional changes. Only comments added.
