From: Ahmad Fatoum a.fatoum@pengutronix.de Date: Thu, 11 Jun 2020 21:17:44 +0200 Subject: [PATCH] watchdog: f71808e_wdt: remove use of wrong watchdog_info option
The flags that should be or-ed into the watchdog_info.options by drivers all start with WDIOF_, e.g. WDIOF_SETTIMEOUT, which indicates that the driver's watchdog_ops has a usable set_timeout.
WDIOC_SETTIMEOUT was used instead, which expands to 0xc0045706, which equals:
WDIOF_FANFAULT | WDIOF_EXTERN1 | WDIOF_PRETIMEOUT | WDIOF_ALARMONLY | WDIOF_MAGICCLOSE | 0xc0045000
These were so far indicated to userspace on WDIOC_GETSUPPORT. As the driver has not yet been migrated to the new watchdog kernel API, the constant can just be dropped without substitute.
