[ Upstream commit 34596ba380b03d181e24efd50e2f21045bde3696 ]

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.
