[PATCH v2 0/5] watchdog: Do not use 'dev' from watchdog_device in watchdog drivers

[Guenter Roeck]

The 'dev' variable in watchdog drivers has a different lifetime than the
watchdog character device and should therefore not be used by watchdog
drivers.

Some of the drivers use the variable to print kernel messages. Those
messages are either dropped or changed to use the parent device.
One driver sets the variable during initialization to the watchdog
driver's parent device, which is wrong and was removed.

v2: Use parent device for dev_XXX messages instead of pr_XXX.
