Thanks for your feedback.

Let me point out in response to the request to squash patches together
that this wish doesn't seem to be the universal right thing to do.

Last time I did a conversion grouped by subsystem, one of the replies
was:

	Reviewed-by: ...
	if you split on per driver basis.

(https://lore.kernel.org/linux-iio/20220808085526.280066-1-u.kleine-koenig@xxxxxxxxxxxxxx)

The obvious upside of a split per driver is that the individual bits are
easier to review, an Ack can be limited to a certain set of drivers, and
(probably most important): If a driver later gets a commit that needs
backporting, a patch that only touches this single driver can more
easily be backported as a dependency.

Also the request to not send everything at once but keep back some
patches has an obvious downside. I.e. I have to restart yet more often
to rebase + test to get all patches applied in the end. And you could
argue that the sum of the work load on the mail servers doesn't get
smaller in sum if the 600 patches are sent over (say) 2 months.
(To prevent a flame war here: Yeah, I agree there are downsides of a
single big series, too.)

All in all my personal opinion is that the advantages of a split per
driver slightly outweight the disadvantages. But obviously that's
subjective.

I will wait a while before sending updates to this series, so don't
expect a new patch very soon. (This has the nice effect that it gives
you some time to reconsider your argument and maybe apply the patches as
they are now, preventing another mail to the lists with the cumulated
macintosh changes ;-)

Best regards
Uwe
