Subject: [PATCH] usb: musb: Fix missing of_node_put() in omap2430_probe
Date: Wed, 9 Mar 2022 11:10:33 +0000 [thread overview]
Message-ID: <20220309111033.24487-1-linmq006@gmail.com> (raw)
The device_node pointer is returned by of_parse_phandle() with refcount
incremented. We should use of_node_put() on it when done.
Fixes: 8934d3e4d0e7 ("usb: musb: omap2430: Don't use omap_get_control_dev()")
