19-19: Verify kernel version 6.6.73 and review changelogs for breaking changes.

The kernel version update looks good. Let's verify the version exists and check for any breaking changes.

Run the following script to verify the kernel version and fetch the changelog:

✅ Verification successful

Kernel version 6.6.73 verified - contains only overlayfs-related fixes

The version exists as a legitimate longterm release. Changelog shows only defensive changes (reverts of problematic overlayfs patches) with no breaking changes.

19-19: LGTM! Kernel version update is consistent.

The kernel version update to 6.6.73 is consistent with the PR objectives and other configuration files. The Rockchip platform compatibility verification from the ODROID-M1 review will cover this board as well since it uses a similar SoC (RK3566 vs RK3568).

buildroot-external/configs/green_defconfig (1)

19-19: LGTM! Kernel version bump from 6.6.71 to 6.6.73.

The version update aligns with the PR objectives and maintains compatibility within the 6.6.y branch.

  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
