Subject: [PATCH v4 01/13] platform/x86: asus-wmi: Fix hwmon device cleanup
Date: Tue, 14 May 2019 20:50:30 +0200 [thread overview]
Message-ID: <e0f78773-518b-b62d-3d95-12225724ea5f@gmail.com> (raw)
In-Reply-To: <c8cdb347-e206-76b2-0d43-546ef660ffb7@gmail.com>
The driver does not clean up the hwmon device on exit or error. To
reproduce the bug, repeat rmmod, insmod to verify that device number
/sys/devices/platform/asus-nb-wmi/hwmon/hwmon?? grows every time. Replace
call for registering device with devm_* version that unregisters it
automatically.
