All modules that need CONFIG_CRC32 already select it, so there is no
need to bother users about the option, nor to default it to y.

My memory from 10-20 years ago could be foggy, but ISTR that someone made at least
CRC16 and CRC32 user-selectable in order to support out-of-tree modules...
FWIW.
But they would not need to be default y.

That's not supported by upstream, though.

Which part is not supported by upstream?

Having prompts for library kconfig options solely because out-of-tree modules
might need them.

Well, I think that is was supported for many years. I don't see how it would become
unsupported all of a sudden. IMHO.

Most kernel-internal options aren't user-selectable, though. It's mainly just
some older ones that were made user-selectable for some reason, and that is a
mistake that has been getting cleaned up over time.
Consider that the upstream community has no visibility into out-of-tree modules
in general, so there is no reasonable policy that could be applied in deciding
which options should be user-selectable purely for the benefit of out-of-tree
modules. The only reasonable policy is to consider in-tree users only. Just
like we don't add EXPORT_SYMBOL() just because an out-of-tree module wants it.
And of course downstreams always can, and do, just add a new kconfig option that
selects any non-visible options they want.

Doing crap for out of tree modules was never in any way supported.
Occasional sloppy maintainers let it slip in but we always fix it ASAP
when noticed.

All modules that need CONFIG_CRC_ITU_T already select it, so there is no
need to bother users about the option.

Previous commits removed all the original CRC kconfig help text, since
it was oriented towards people configuring the kernel, and the options
are no longer user-selectable. However, it's still useful for there to
be help text for kernel developers. Add this.

I usually document hidden options using comments instead of the help
text to clearly distinguish them for visible options. Not sure if there
is a general preference either way, I just through I'd drop this here.

Using comments makes sense to me. But on past patches affecting hidden options,
I've had people ask for help text specifically. It also looks like help text is
more common than comments, even considering just hidden options. So I think
I'll keep this patch as-is.

Now that LIBCRC32C does nothing besides select CRC32, make every option
that selects LIBCRC32C instead select CRC32 directly. Then remove
LIBCRC32C.
