Subject: [PATCH] ARM: at91: pm: Add of_node_put() before goto
Date: Thu, 14 Oct 2021 04:45:55 -0400 [thread overview]
Message-ID: <20211014084555.21422-1-wanjiabing@vivo.com> (raw)
Fix following coccicheck warning:
./arch/arm/mach-at91/pm.c:643:1-33: WARNING: Function
for_each_matching_node_and_match should have of_node_put() before goto
Early exits from for_each_matching_node_and_match should decrement the
node reference counter.
