[WATCHDOG] driver-for-ibm-automatic-server-restart-watchdog-fix2.patch
The device/watchdog has a fixed timeout/heartbeat. So we don't support the WDIOC_SETTIMEOUT ioctl call and we also may not set the WDIOF_SETTIMEOUT flag. Cc: Andrey Panin <pazke@donpac.ru> Cc: Andrew Morton <akpm@osdl.org> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
