Note that this doesn't help when it's reverse-selected by others.
The same is true for an item with a prompt, but the item like this without prompt is supposed to be reverse-selected only, so adding "depends on" there is merely a placeholder.
That being said, currently the only way to guarantee the dependency by a reverse-selection is to put the depends-on to the selecting item, not to the selected item.
It's a generic problem of the kbuild implementation, and people know of it over a decade. It was discussed in the previous Plumbers conference, and developers agreed to improve the situation, so it may be a bit better in near future.
Hmm.. indeed thanks for your feedback. So, should I send v2 patch ? or as-is is OK at this point ?
While it doesn't prevent the symbol from being selected this will generate a warning if the symbol is selected while its dependencies are not met. So I'd say it is still useful to have.
