From: Ahmad Fatoum <a.fatoum@pengutronix.de>
commit e871e93fb08a619dfc015974a05768ed6880fd82 upstream.
The driver supports populating bootstatus with WDIOF_CARDRESET, but so far userspace couldn't portably determine whether absence of this flag meant no watchdog reset or no driver support. Or-in the bit to fix this.
