Hello,

Thanks for the patch, but Vladimir had already sent it, and it had
already been merged in Buildroot master. See more comments below

The Change-Id shouldn't appear in Buildroot commits, as it's not
relevant for the Buildroot development process.

This cherry picked message also doesn't make much sense in this
context.
