I couldn't find the original patch email for this commit to reply. Anyhow, the above commit makes buildroot unhappy. I see this when trying to build any of my buildroot environments: scripts/dtc/Makefile:23: *** dtc needs libyaml for DT schema validation support. Install the necessary libyaml development package.. Stop. I think this is some mess with pkg-config from somewhere (the host distro, the buildroot host side,..) saying libyaml is available but when the build actually happens the header it wants isn't actually where it thinks. I think this is a pre-existing problem with buildroot. buildroot takes a list of the dtbs that you want to build and keep in it's config and calls make with that list in the kernel build. So this commit causes this issue to trigger when buildroot tries to build the configured dtbs. Not sure what the fix is and I think it's probably a buildroot problem. Cheers, Daniel
