That's not an error value. If you have a -1 ID, you're only telling the
kernel "this is only omap_wdt platform_device I have", which means that
it will look in sysfs as:

/sys/devices/platform/omap_wdt/

if you have an ID >= 0, it will look as:

/sys/devices/platform/omap_wdt.0/
/sys/devices/platform/omap_wdt.1/
/sys/devices/platform/omap_wdt.2/

etc, that's all.
