Subject: [PATCH] hwmon: (w83627ehf) Fix a resource leak in probe
Date: Mon, 21 Sep 2020 12:52:12 +0000 [thread overview]
Message-ID: <20200921125212.GA1128194@mwanda> (raw)
Smatch has a new check for resource leaks which found a bug in probe:
drivers/hwmon/w83627ehf.c:2417 w83627ehf_probe()
warn: 'res->start' not released on lines: 2412.
We need to clean up if devm_hwmon_device_register_with_info() fails.
Fixes: 266cd5835947 ("hwmon: (w83627ehf) convert to with_info interface")
