Subject: [PATCH 0/9] i2c: Switch .probe() to not take an id parameter

Hello,

back in 2016 a conversion was started to drop the id parameter from the
.probe() callback of i2c drivers. This series (somewhat) completes this
quest: As of next-20230224 all but very few drivers are converted to the
temporary .probe_new() callback such that .probe() can be changed
accordingly. There are currently no new drivers in next making use of
the old .probe() callback.

The first 6 patches convert the remaining drivers. Three of them have
their maintainer's ack, I didn't get feedback for the other three.
The Link footer in these patches document the earlier submissions.

The 7th patch changes .probe() to the prototype without the id
parameter. The remaining two patches convert the drivers contained in
the i2c subsystem to the new .probe().

I chose v6.2 as a base for this series but note that there a few more
drivers in there that are still unconverted. Linus Torvalds's tree (as
of d2980d8d826554fa6981d621e569a453787472f8) contains 60 more
conversions after v6.2. In next there is another set of 22 conversions
that are required before this series can go in. My expectation is that
these 82 change sets will be all contained in 6.3-rc1 such that this
series can be applied on top of that tag.

For reference the complete set of patches is available at

	https://git.pengutronix.de/git/ukl/linux i2c-probe-new

I'll rebase that from time to time such that the set of remaining
patches can be checked there.

@Wolfram: It would be great to get this series into next soon after
v6.3-rc1 is published, maybe with a tag for other subsystems to pull.
(This would be required if new drivers want to make use of the new
.probe() callback only.)

I intend to convert all drivers to the new .probe() callback after this
series landed and then eventually drop .probe_new() to complete the
effort.

Best regards
Uwe
