kconfig: document Kconfig source file comments
I saw this type of Kconfig construct on LKML: config SYMBOOL #bool "prompt string" default y and wondered what it does. Then I wondered if '#' comments are even documented. They aren't, so add a little doc for that. Ah, good. kconfig says: arch/x86/Kconfig:2942:warning: config symbol defined without type Signed-off-by: Randy Dunlap <rdunlap@infradead.org> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
