Subject: [PATCH] soc: qcom: ocmem: Fix missing put_device() call in of_get_ocmem
Date: Fri, 7 Jan 2022 07:31:26 +0000 [thread overview]
Message-ID: <20220107073126.2335-1-linmq006@gmail.com> (raw)
The reference taken by 'of_find_device_by_node()' must be released when
not needed anymore.
Add the corresponding 'put_device()' in the error handling path.
Fixes: 01f937ffc468 ("soc: qcom: ocmem: don't return NULL in of_get_ocmem")
