Subject: [PATCH] fsl/fman: Fix missing put_device() call in fman_port_probe
Date: Thu, 30 Dec 2021 12:26:27 +0000 [thread overview]
Message-ID: <20211230122628.22619-1-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 and error handling paths.
Fixes: 18a6c85fcc78 ("fsl/fman: Add FMan Port Support")
