[GIT PULL] i2c for v7.4, part 2

[Andi Shyti]

Hi Linus,

as anticipated, here is the second part of the I2C pull request
for v7.4.

This round introduces dynamic transfer timeouts in the I2C core,
already used by qcom-geni. There is also support for additional
transfer modes in imx and a handful of driver fixes.

I've also merged Igor's Rust I2C pull request, which removes an
unsafe conversion.

The branch is rebased on top of your part 1 I2C merge[*].

I'll now start queuing patches for a possible third week of the
merge window. Otherwise, they will go into v7.5.

Thanks and wishing you a good rest of your holidays,
Andi

i2c for v7.4, part 2

This second part introduces dynamic transfer timeouts in the I2C
core, already used by qcom-geni. Alongside some driver
improvements and fixes, it also brings in the Rust I2C pull
request.

Core:

- core, qcom-geni: add and use a dynamic timeout helper
- acpi: fix adapter reference leak when creating I2C clients

Drivers:

- imx: support reversed address direction and no-start transfers
- designware: queue block data reads once length is known
- mt7621: skip the second data register for chunks up to 4 bytes
- sh_mobile: ensure IRQs are freed before unmapping registers

Rust:

- Remove unsound device-to-client reference conversion
