From: Alexander Sverdlin Date: Thu, 7 Nov 2024 20:38:28 +0000 (+0100) Subject: watchdog: rti: of: honor timeout-sec property X-Git-Tag: v6.13-rc2~27^2 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=4962ee045d8f06638714d801ab0fb72f89c16690;p=thirdparty%2Fkernel%2Flinux.git watchdog: rti: of: honor timeout-sec property Currently "timeout-sec" Device Tree property is being silently ignored: even though watchdog_init_timeout() is being used, the driver always passes "heartbeat" == DEFAULT_HEARTBEAT == 60 as argument. Fix this by setting struct watchdog_device::timeout to DEFAULT_HEARTBEAT and passing real module parameter value to watchdog_init_timeout() (which may now be 0 if not specified).
