3.16.48-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Eric Anholt <eric@xxxxxxxxxx>
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")
