[PATCH AUTOSEL 4.14 11/17] mips: mti-malta: Fix refcount leak in malta-time.c

From: Sasha Levin
Date: Mon Jun 27 2022 - 22:34:06 EST


From: Liang He <windhl@xxxxxxx>

[ Upstream commit 608d94cb84c42585058d692f2fe5d327f8868cdb ]

In update_gic_frequency_dt(), of_find_compatible_node() will return
a node pointer with refcount incremented. We should use of_node_put()
when it is not used anymore.
