This may cause a warning when pm_runtime_enable checks for the count match. Also fixes the error /build/watchdog # insmod omap_wdt.ko [ 44.999389] omap_wdt omap_wdt: Unbalanced pm_runtime_enable! [ 45.011047] OMAP Watchdog Timer Rev 0x00: initial timeout 60 sec /build/watchdog # Attempting to fix the same by calling pm_runtime_disable.
