Subject: [PATCH] ALSA: hda: intel-sdw-acpi: fix usage of device_get_named_child_node()
Date: Fri, 26 Apr 2024 10:27:31 -0500 [thread overview]
Message-ID: <20240426152731.38420-1-pierre-louis.bossart@linux.intel.com> (raw)
The documentation for device_get_named_child_node() mentions this
important point:
"
The caller is responsible for calling fwnode_handle_put() on the
returned fwnode pointer.
"
Add fwnode_handle_put() to avoid a leaked reference.
