Subject: [PATCH 5.4 158/320] ARM: shmobile: rcar-gen2: Add missing of_node_put()
From: Wan Jiabing <wanjiabing@...o.com>
[ Upstream commit 85744f2d938c5f3cfc44cb6533c157469634da93 ]
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.
