[PATCH AUTOSEL 4.4 30/63] SoC: imx-sgtl5000: add missing put_device()

[Sasha Levin]

From: Wen Yang <yellowriver2010@hotmail.com>

[ Upstream commit 8fa857da9744f513036df1c43ab57f338941ae7d ]

The of_find_device_by_node() takes a reference to the underlying device
structure, we should release that reference.

Detected by coccinelle with the following warnings:
./sound/soc/fsl/imx-sgtl5000.c:169:1-7: ERROR: missing put_device;
call of_find_device_by_node on line 105, but without a corresponding
object release within this function.
./sound/soc/fsl/imx-sgtl5000.c:177:1-7: ERROR: missing put_device;
call of_find_device_by_node on line 105, but without a corresponding
object release within this function.
