Hi!

This is an automated message. This series looks like a fix, but its
commit messages seem to be missing some information:

  - How the issue was discovered, e.g. hit in production, hit during
    development, syzbot report, manual code inspection, LLM or static
    analysis tool scan.

  - Whether the issue was actually triggered, or is only theoretical
    (e.g. found by code inspection). If it was triggered please include
    the symptoms, like the stack trace or error messages.

Please do not repost the series just to address the above. Instead,
reply to this email with the missing information, so that reviewers
can take it into account. If the series needs another revision for
other reasons, please include the information in the commit messages
then.

The evaluation is done by an LLM so it may be wrong, if you think
that is the case please reply and explain.

Hi,

This issue was discovered when upgrading an embedded device from kernel 5.10 to 6.16.

The device was using a KSZ8765 device tree configuration and the
corresponding hardware, but during boot the kernel incorrectly detected
it as a KSZ8795.

The issue was reproduced during testing. The relevant boot messages were:

    ksz-switch spi0.0: found switch: KSZ8795, rev 0
    ksz-switch spi0.0: Device tree specifies chip KSZ8765 but found KSZ8795, please fix it!

The fix was then tested manually.

Thanks,
