I already have a local patch for this and "reset" bindings. But I'm
holding off on adding support for new properties till fw_devlink=on
fully lands in 5.13. Trying to avoid inadvertently adding new
dependency issues. For example, the remote_endpoint binding I added to
fix one issue caused more dependency issues. So far I've fixed them
all.
So, yeah, temporary Nak for this.
