[PATCH 00/23] iio: make masklength __private (final round)

[Nuno Sa via B4 Relay <devnull+nuno.sa.analog.com@kernel.org>]

Hi Jonathan,

Here it goes the final conversion round.  On the testing branch a git
grep:

git grep "\->masklength"

Gives no more users so hopefully I did it right :).

Not entirely related with this but I'll mention it anyways :). Looking
at the other [INTERN] fields, I see:

* active_scan_mask: which seems to be pretty similar to masklength;
* scan_timestamp: Has some apparently valid  users;
* scan_bytes: Also has a few users;
* trig: may need a bit more inspection.

The first 3 look like valid RO fields that drivers are allowed to
access. I mean, for scan_bytes I guess drivers could calculate that
based on the active_scan_mask but I think that's just not worth it given
the core already did it for us.
 
So I wonder if a similar work would be valuable? scan_timestamp and
scan_bytes would be pretty trivial but for active_scan_mask we do have
lots of users (but also trivial I think).

For Trig, most of the writes are drivers doing

indio_dev->trig = iio_trigger_get(data->trig);

So we either assume it's public or remove that line from drivers. Though
that could break userland apps relying on some trigger to be
automatically set after device probe. We can anyways have another helper
to do that for drivers (not sure this field is accessed in some
fastpath).

Also need to better check if there are any readers for it.

Anyways, it would be nice to get your inputs on the last [INTERNAL] fields
in struct iio_dev

Also want to mention that I deliberately removed some mailing lists
given by get_maintainers as this is fairly simple and so I don't think
the "spam" is worth it :).
