If anyone has any objections, please let me know. ------------------ From: Liang He [ Upstream commit b9bbbf4979073d5536b7650decd37fcb901e6556 ] In mpc5xxx_fwnode_get_bus_frequency(), we should add fwnode_handle_put() when break out of the iteration fwnode_for_each_parent_node() as it will automatically increase and decrease the refcounter.
