Subject: [PATCH] powerpc/mpc5xxx: Add missing fwnode_handle_put()
Date: Wed, 22 Mar 2023 11:04:23 +0800 [thread overview]
Message-ID: <20230322030423.1855440-1-windhl@126.com> (raw)
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")
