From 8a7b76be691fa30c7650b8e08aae8a7990c93779 Mon Sep 17 00:00:00 2001 From: Guenter Roeck Date: Thu, 24 Dec 2015 14:22:02 -0800 Subject: [PATCH] watchdog: gpio: Do not use device pointer from struct watchdog_device 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.
