From: Stefan Eichenberger Date: Tue, 6 Apr 2021 12:12:47 +0000 (+0200) Subject: watchdog: imx_sc_wdt: fix pretimeout X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=854478a381078ee86ae2a7908a934b1ded399130;p=linux.git watchdog: imx_sc_wdt: fix pretimeout If the WDIOF_PRETIMEOUT flag is not set when registering the device the driver will not show the sysfs entries or register the default governor. By moving the registering after the decision whether pretimeout is supported this gets fixed.
