Subject: [PATCH v1 1/3] usb: typec: intel_pmc_mux: Put fwnode in error case during ->probe()
Date: Sun, 6 Jun 2021 23:09:09 +0300 [thread overview]
Message-ID: <20210606200911.32076-1-andy.shevchenko@gmail.com> (raw)
device_get_next_child_node() bumps a reference counting of a returned variable.
We have to balance it whenever we return to the caller.
Fixes: 6701adfa9693 ("usb: typec: driver for Intel PMC mux control")
