Subject: [PATCH] ARM: imx6: add missing put_device() call in imx6q_suspend_init()
Date: Thu, 4 Jun 2020 20:54:49 +0800
Message-ID: <20200604125449.3917164-1-yukuai3@huawei.com> (raw)

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.
