However, many wdt devices does not set its 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, mpc8xxx, octeon, softdog and w83627hf -- They do not have any parent. Not sure, how we can we identify driver for these devices.
