If anyone has any objections, please let me know. ------------------ From: Akhilesh Patil [ Upstream commit e8cfc524eaf3c0ed88106177edb6961e202e6716 ] Check if watchdog device supports WDIOF_KEEPALIVEPING option before entering keep_alive() ping test loop. Fix watchdog-test silently looping if ioctl based ping is not supported by the device. Exit from test in such case instead of getting stuck in loop executing failing keep_alive() watchdog_info: identity: m41t93 rtc Watchdog firmware_version: 0 Support/Status: Set timeout (in seconds) Support/Status: Watchdog triggers a management or other external alarm not a reboot Watchdog card disabled. Watchdog timeout set to 5 seconds. Watchdog ping rate set to 2 seconds. Watchdog card enabled. WDIOC_KEEPALIVE not supported by this device without this change Watchdog card disabled. Watchdog timeout set to 5 seconds. Watchdog ping rate set to 2 seconds. Watchdog card enabled. Watchdog Ticking Away!
