[PATCH 4.19 052/220] watchdog: sama5d4: fix timeout-sec usage

From: Greg Kroah-Hartman
Date: Fri Nov 22 2019 - 05:58:04 EST


From: Romain Izard <romain.izard.pro@xxxxxxxxx>

[ Upstream commit 2e0432f8f8ad11b4bd208445360220efa5b37d82 ]

When using watchdog_init_timeout to update the default timeout value,
an error means that there is no "timeout-sec" in the relevant device
tree node.

This should not prevent binding of the driver to the device.
