A couple of initial comments: layer.conf contains `PREFERRED_VERSION_linux-yocto ?= "5.10%"`. It'd be better to leave that out and in the readme say that users need to add this in their distro or local conf. That would bring the layer in line with best practices and what's needed for Yocto Project Compatible status as adding simply a layer to a build should not result in changes to the images you build. The layer needs a COPYING or LICENSE file. It'd be good to explicitly say how contributions to the layer can be made - should this be by GitHub pull request or via a mailing list?
