6.6-stable review patch.  If anyone has any objections, please let me know.

[ Upstream commit 59ed5e2d505bf5f9b4af64d0021cd0c96aec1f7c ]

Useful where the fwnode_handle was obtained from a call such as
fwnode_find_reference() as it will safely do nothing if IS_ERR() is true
and will automatically release the reference on the variable leaving
scope.
