watchdog: f71808e_wdt: fix inaccurate report in WDIOC_GETTIMEOUT
[ Upstream commit 164483c735190775f29d0dcbac0363adc51a068d ]
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")
