[PATCH v2 3/3] watchdog: pretimeout: record PSC reason on watchdog pretimeout

[Faruque Ansari]

Update the PSC reset reason by invoking set_psc_reason(PSCR_WATCHDOG_PRETIMEOUT)
from watchdog_notify_pretimeout() before either the panic or noop governor
runs, so the reset cause is committed to persistent storage before the
system goes down.
