Readded the of_match_table.
Added default cases where it was necessary.
Used mutex where it was necessary.
Added conversion to milli-degrees and milli-seconds.

MAX31827 is a low-power temperature switch with I2C interface.
The device is a ±1°C accuracy from -40°C to +125°C
(12 bits) local temperature switch and sensor with I2C/SM-
Bus interface. The combination of small 6-bump wafer-lev-
el package (WLP) and high accuracy makes this temper-
ature sensor/switch ideal for a wide range of applications.

Guenter asked for changelog... What do you expect us to do here?
Best regards,

Hm, now I see the tag - did you just ignore it or did you change something?
Standard message follows:
This is a friendly reminder during the review process.
It looks like you received a tag and forgot to add it.
If you do not know the process, here is a short explanation:
Please add Acked-by/Reviewed-by/Tested-by tags when posting new
versions. However, there's no need to repost patches *only* to add the
tags. The upstream maintainer will do that for acks received on the
version they apply.
https://elixir.bootlin.com/linux/v5.17/source/Documentation/process/submitting-patches.rst#L540
If a tag was not added on purpose, please state why and what changed.
Best regards,
Krzysztof
