Subject: [PATCH AUTOSEL 5.4 17/27] mips: mti-malta: Fix refcount leak in malta-time.c
Date: Mon, 27 Jun 2022 22:24:03 -0400	[thread overview]
Message-ID: <20220628022413.596341-17-sashal@kernel.org> (raw)
In-Reply-To: <20220628022413.596341-1-sashal@kernel.org>

From: Liang He <windhl@126.com>

[ 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.
