I was poking around that git repo and didn't see any commit with this title. This breaks fw_devlink in a severe manner, so I want to make sure it gets into 5.18. -Saravana -Saravana

Look in linux-next: 117ef574074d ("device property: Fix recent breakage of fwnode_get_next_parent_dev()") Rafael's tree is not my tree :) thanks, greg k-h

Due to a subtle typo, instead of commit 87ffea09470d ("device property: Introduce fwnode_for_each_parent_node()") being a no-op change, it ended up causing the display on my sc7180-trogdor-lazor device from coming up unless I added "fw_devlink=off" to my kernel command line.
