Subject: [PATCH v2 1/3] usb: typec: intel_pmc_mux: Put fwnode in error case during ->probe()
Date: Mon, 7 Jun 2021 23:50:05 +0300 [thread overview]
Message-ID: <20210607205007.71458-1-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")
