Subject: [PATCH v5 1/7] watchdog: f71808e_wdt: fix inaccurate report in WDIOC_GETTIMEOUT
Date: Mon, 9 Aug 2021 18:20:31 +0200 [thread overview]
Message-ID: <5e17960fe8cc0e3cb2ba53de4730b75d9a0f33d5.1628525954.git-series.a.fatoum@pengutronix.de> (raw)
In-Reply-To: <cover.3654d10d79751f1b01adc9403f9840543df4bcc4.1628525954.git-series.a.fatoum@pengutronix.de>
The fintek watchdog timer can configure timeouts of second granularity
only up to 255 seconds. Beyond that, the timeout needs to be configured
with minute granularity. WDIOC_GETTIMEOUT should report the actual
timeout configured, not just echo back the timeout configured by the
user. Do so.
Fixes: 96cb4eb019ce ("watchdog: f71808e_wdt: new watchdog driver for Fintek F71808E and F71882FG")
