6.5-stable review patch. If anyone has any objections, please let me know.
------------------
From: Liang He <windhl@xxxxxxx>
[ 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.
Fixes: de06fba62af6 ("powerpc/mpc5xxx: Switch mpc5xxx_get_bus_frequency() to use fwnode")
