Subject: [PATCH master 1/2] sandbox: watchdog: don't return positive values from set_timeout
Date: Mon, 26 Apr 2021 13:34:07 +0200	[thread overview]
Message-ID: <20210426113408.24903-1-a.fatoum@pengutronix.de> (raw)

linux_watchdog_set_timeout() does return alarm(), which can never fail
and returns either zero or a positive value.

watchdog::set_timeout on the other hand should return either 0 or
a negative number on error.

Ignore linux_watchdog_set_timeout()'s return value, so
watchdog_set_timeout propagates the correct value.

This fixes an issue where seconds_to_expire wasn't updated on
subsequent pings of this watchdog.
