Subject: [PATCH AUTOSEL 4.19 040/209] watchdog: sama5d4: fix timeout-sec usage

From: Romain Izard <romain.izard.pro@...il.com>

[ 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.

Fixes: 976932e40036 ("watchdog: sama5d4: make use of timeout-secs provided in devicetree")
