Subject: [PATCH] ARM: shmobile: Add missing of_node_put()
Date: Sun, 17 Oct 2021 21:45:03 -0400	[thread overview]
Message-ID: <20211018014503.7598-1-wanjiabing@vivo.com> (raw)

Fix following coccicheck warning:
./arch/arm/mach-shmobile/regulator-quirk-rcar-gen2.c:156:1-33: Function
for_each_matching_node_and_match should have of_node_put() before break
and goto.

Early exits from for_each_matching_node_and_match should decrement the
node reference counter.
