Hi Guenter,

Thank you for your patient review.
This is v3 of the lenovo-ec-sensors fix series.

Changes from v2:

- Corrected bug description and Remove unnecessary {}.
- Reproduce patch 0002 based 0001 changed.

Patch 1 converts manual request_region()/release_region() calls to
devm_request_region(), eliminating a double-release on the probe error
path and a release-after-use window on module exit.

Patch 2 fixes the EC "MCHP" signature check that used && instead of ||,
which caused the validation to accept a non-Microchip EC if any single
byte of the expected 4-byte signature happened to match.

Both patches apply cleanly against v7.1-rc3 and pass checkpatch with
0 errors, 0 warnings.
