[ 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.

This was found by coccicheck:
./arch/arm/mach-omap2/display.c, 272, 1-7, ERROR missing put_device;
call of_find_device_by_node on line 258, but without a corresponding
object release within this function.

Move the put_device() call before the if judgment.
