Thanks for the patch. However, the upstream feedback was that your
patch wasn't quite correct. So I took upstream's feedback into
account, created a new patch and a new merge request.

Aside from that, your Buildroot message was missing some important
information: since when the problem was happening, and a reference to
the autobuilder issues being fixed.

The final commit is:

  https://gitlab.com/buildroot.org/buildroot/-/commit/c0fd48dc2651a8c60ca82bef760670b3a62ab621

Thanks a lot,

Thomas
