Subject: [PATCH v2 4/5] watchdog: mena21: Do not use device pointer from struct watchdog_device
Date: Thu, 24 Dec 2015 14:22:03 -0800	[thread overview]
Message-ID: <1450995724-17758-5-git-send-email-linux@roeck-us.net> (raw)
In-Reply-To: <1450995724-17758-1-git-send-email-linux@roeck-us.net>

The device pointer in struct watchdog_device has a different lifetime
than the driver code and should not be used in drivers. Use the pointer
to the parent device instead.
