[PATCH v2 4/5] watchdog: mena21: Do not use device pointer from struct watchdog_device

From: Guenter Roeck
Date: Thu Dec 24 2015 - 17:22:43 EST


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.
