commit fedf266f9955d9a019643cde199a2fd9a0259f6f upstream.
The bcm_kona_wdt_set_resolution_reg() call takes the spinlock, so
initialize it earlier. Fixes a warning at boot with lock debugging
enabled.
Fixes: 6adb730dc208 ("watchdog: bcm281xx: Watchdog Driver")

/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.

The seq_printf return value, because it's frequently misused,
will eventually be converted to void.
See: commit 1f33c41c03da ("seq_file: Rename seq_overflow() to
seq_has_overflowed() and make public")

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