[PATCH AUTOSEL 6.19-6.18] platform/x86: oxpec: Add support for Aokzoe A2 Pro

[Sasha Levin]

From: Antheas Kapenekakis <lkml@xxxxxxxxxxx>

[ Upstream commit cd0883055b04586770dab43c64159348bf480a3e ]

Aokzoe A2 Pro is an older device that the oxpec driver is missing the
quirk for. It has the same behavior as the AOKZOE A1 devices. Add a
quirk for it to the oxpec driver.

LLM Generated explanations, may be completely bogus:

This is important context. The driver was originally `drivers/hwmon/oxp-
sensors.c` (added in late 2022, so present in 6.1+ stable trees) and was
moved/renamed to `drivers/platform/x86/oxpec.c` in April 2025. This
means:

- **For stable trees based on kernels before the move (6.1.y, 6.6.y,
  6.12.y likely)**: The file is at `drivers/hwmon/oxp-sensors.c`, and
  this patch won't apply cleanly. A backport would need to target the
  old location.
- **For newer stable trees (6.15.y+)**: The patch would apply cleanly.

The driver rename is a significant obstacle for backporting to older
stable trees, though the fix itself is trivial.

### Verification:
- Confirmed the driver was originally `drivers/hwmon/oxp-sensors.c`
  (added Nov 2022, present since ~v6.2)
- Confirmed it was moved to `drivers/platform/x86/oxpec.c` in commit
  `3012bb39001c` (April 2025)
- Confirmed the change is a pure DMI table entry addition using existing
  `aok_zoe_a1` enum value
- Confirmed `aok_zoe_a1` is already used by two other AOKZOE entries (A1
  AR07, A1 Pro)
- Confirmed the patch was reviewed by Ilpo Järvinen (platform/x86
  maintainer)
- The driver's presence in older stable trees is under a different
  filename, meaning this patch would need adjustment for backporting to
  older stable branches

### Summary

This is a textbook hardware quirk addition — a trivial DMI table entry
that enables an existing driver to support a specific device (Aokzoe A2
Pro). It has zero risk of regression, fixes a real hardware support gap
for actual users, and is reviewed by the subsystem maintainer. The only
caveat is that it would need path adjustment for older stable trees
where the driver is still at `drivers/hwmon/oxp-sensors.c`, but that's a
mechanical change. This meets all stable kernel criteria.

**YES**
