mfd: syscon: Call of_node_put() only when of_parse_phandle() takes a ref ...
[ Upstream commit d2b0680cf3b05490b579e71b0df6e07451977745 ]
of_parse_phandle() returns a device_node with refcount incremented, which
the callee needs to call of_node_put() on when done. We should only call
of_node_put() when the property argument is provided though as otherwise
nothing has taken a reference on the node.
Fixes: 45330bb43421 ("mfd: syscon: Allow property as NULL in syscon_regmap_lookup_by_phandle")
