Hi Vincent,

thanks for taking care of this upstream ; it was a quick acceptance by sysrepo.

@Thomas,

Absolutely! Could you send an updated Buildroot patch, which
integrates this upstream sysrepo patch?

Thanks for the work on this topic!

Do you mean dropping the patch file and making the package use the devel branch?

No, backport the patch to whatever stable version the Buildroot
package is using, and add the patch into package/<pkg>/. Don't forget
the Upstream: tag in the patch, pointing to the upstream commit.

Thanks!

Ok. This is what I did in this patch. I added a patch file with the fix and the Upstream tag.
