Subject: [PATCH AUTOSEL 4.14 1/5] ARM: OMAP2+: hwmod: Add of_node_put() before break

From: Wan Jiabing <wanjiabing@...o.com>

[ Upstream commit 80c469a0a03763f814715f3d12b6f3964c7423e8 ]

Fix following coccicheck warning:
./arch/arm/mach-omap2/omap_hwmod.c:753:1-23: WARNING: Function
for_each_matching_node should have of_node_put() before break

Early exits from for_each_matching_node should decrement the
node reference counter.
