It's been a week, why hasn't the review been conducted yet? Could it be that the submitted patch will cause issues with the source code compilation?

Our review capacity is very small. We try to get more people on this https://forum.armbian.com/staffapplications/application/23-code-reviewer/ but there is sadly not much interest. Review is hard and inglorious work ... I am open for ideas what else we could try?

I made a comment about concerns but whatever...
