#1647375 — [PATCH 1/3] pinctrl: samsung: clean up modular vs. non-modular distinctions

Fixups here tend to be more all over the map vs. some of the other
repeated/systematic ones we've seen elsewhere.

We remove module.h from code that isn't doing anything modular at
all;  if they have __init sections, then replace it with init.h

A couple drivers have module_exit() code that is essentially orphaned,
and so we remove that.

There are no module_init replacements, so we have no concerns wrt.
initcall ordering changes as per some of the other cleanups.

Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.

We also delete the MODULE_LICENSE tag etc. since all that information
was (or is now) contained at the top of the file in the comments.

These are quite old entries of maintainers. I guess you add Cc-entries
once per git commit but no problem - I have it from the lists.

Thanks, applied.

Best regards,
Krzysztof

Actually what happend is it got sent quite some time ago, but Linus
didn't merge it because he wanted some Acks[1] and a resend.  Shortly
after Sylwester provided an ack.

So with that in mind, I decided to restart with the most simple pinctrl
patches 1st, and hence it took a while to finally get back to this one
in the final series.  But I didn't want to change an ack'd patch.

Not that it matters, but just in case you were curious.

Thanks,
Paul.
