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. Fix the typo.

Has this been picked up by one of the driver-core branches yet? 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.

Look in linux-next:
	117ef574074d ("device property: Fix recent breakage of fwnode_get_next_parent_dev()")

Rafael's tree is not my tree :)
