[PATCH v2 0/8] IIO: ADCs: Sparse friendly claim of direct mode

[Jonathan Cameron <jic23@kernel.org>]

From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

Resend of remaining unreviewed updates in drivers/iio/adc/*

I will eventually just apply these, but I'd much rather someone
else took a quick look to check I haven't done anything stupid!

Note that a number of the drivers touched in this series have no
obvious active maintainer, so it would be much appreciated if anyone
has time to take a look! It is a large series so feel free to review
any you have time to look at rather than feeling you need to look
at the whole thing!

This is effectively part 3 of what will probably be around 5 series
focused on moving from iio_device_claim/release_direct_mode() to
iio_device_claim/release_direct(). The new form is more consistent
with conditional locking semantics and sparse markings have been
added that let us detect miss-balance between claim and release.

More details can be found in the cover letter of the first series:
https://lore.kernel.org/all/20250209180624.701140-1-jic23@kernel.org/

This series focuses on the ADC drivers.
