From 578a3db8717cc9f8e75ca9044084bfd68cc5b223 Mon Sep 17 00:00:00 2001 From: Alexander Sverdlin Date: Thu, 7 Nov 2024 21:38:28 +0100 Subject: [PATCH] watchdog: rti: of: honor timeout-sec property commit 4962ee045d8f06638714d801ab0fb72f89c16690 upstream. 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).
