I believe most drivers do not have this, but either a comment about M
will build a module or nothing at all.

(Yes, yes, I know my drivers do not follow this. I've been meaning to
fix that. :))

Same here. And you should also mention (again) that card drivers are
needed to do anything useful.

Ditto. And until this depends/select business is sorted out, I'd prefer
a select on TIFM_CORE here.


Other than that...

I kind of fail to follow here. Do you want to switch TIFM_CORE -> MMC_TIFM_SD dependency into
MMC_TIFM_SD -> TIFM_CORE + TIFM_7XX1 one? It may be slightly more convenient for users (even
though most are using pre-compiled kernels provided by distribution), but will be logically
incorrect, doesn't it? And then, what will become of memorystick driver?

No no, I want a change from "depends" to "select". That symbolises the
same dependency, but it has slightly different semantics (which it
probably shouldn't, but that's another discussion). With "depends", a
config entry is hidden if its dependencies aren't satisfied. With
"select", it will forcefully enable those dependencies.

>From a user point of view, the former requires knowledge of how all of
these things hangs together (which is expecting a bit much), but the
latter will automatically pull in all the components needed to build the
option the user selects (which is how dependencies should work IMO).
