Krzysztof Sobota cca1e32f9e watchdog: initialize device before misc_register ... [ Upstream commit cb36e29bb0e4b0c33c3d5866a0a4aebace4c99b7 ] When watchdog device is being registered, it calls misc_register that makes watchdog available for systemd to open. This is a data race scenario, because when device is open it may still have device struct not initialized - this in turn causes a crash. This patch moves device initialization before misc_register call and it solves the problem printed below. ------------[ cut here ]------------ WARNING: CPU: 3 PID: 1 at lib/kobject.c:612 kobject_get+0x50/0x54 kobject: '(null)' ((ptrval)): is not initialized, yet kobject_get() is being called.
