[PATCH 00/37] IIO: Sparse friendly claim of direct mode (the rest)

[Jonathan Cameron <jic23@kernel.org>]

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

Firstly, sorry for the huge patch set!

I've run out of signficiant groups to break the remaining patches up into.
Rather than have lots of small series of 5-10 patches, lets just have one
mega one. Feel free to review a subset! I'll nibble away at this as reviews
come in and post a v2 later in the cycle with whatever remains unreviewed
if that is necessary.

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!

This is effectively part 5 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 all the remaining drivers.
The final patch removes the old infrastructure.
