I think of_node_put should be moved out from here and put into
syscon_node_to_regmap and syscon_regmap_lookup_by_compatible.

I guess no, if you want to move of_node_put into syscon_regmap_lookup_by_phandle,
then syscon_regmap_lookup_by_phandle has the same issue.

I guess not.  syscon_regmap_lookup_by_phandle itself calls of_parse_phandle,
and that's where the refcount gets incremented, so syscon_regmap_lookup_by_phandle
should be responsible for calling of_node_put to get the refcount decremented.
