[PATCH 4.19 19/58] ARM: imx6: add missing put_device() call in imx6q_suspend_init()

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

From: yu kuai <yukuai3@huawei.com>

[ Upstream commit 4845446036fc9c13f43b54a65c9b757c14f5141b ]

if of_find_device_by_node() succeed, imx6q_suspend_init() doesn't have a
corresponding put_device(). Thus add a jump target to fix the exception
handling for this function implementation.
