David Cohen 8cbb97ea3e watchdog: intel-mid: add Magic Closure flag
Adding WDIOF_MAGICCLOSE to Intel MID watchdog driver. Once the watchdog
is opened, it makes sense to disable watchdog only if it was gracefully
released.

Pratyush Anand 6551881c86 Watchdog: Fix parent of watchdog_devices
/sys/class/watchdog/watchdogn/device/modalias can help to identify the
driver/module for a given watchdog node. However, many wdt devices do not
set their parent and so, we do not see an entry for device in sysfs for
such devices.

This patch fixes parent of watchdog_device so that
/sys/class/watchdog/watchdogn/device is populated.

Exceptions: booke, diag288, octeon, softdog and w83627hf -- They do not
have any parent. Not sure, how we can identify driver for these devices.

A platform_driver does not need to set an owner, it will be populated by the
driver core.
