Why removing especially WDIOF_MAGICCLOSE (and the timer needed for that)? This is a feature removal. Without there isn't even a need for nowayout option as it is implicitly set anyway.
Nevertheless I would prefere keeping the timer to allow a user to let the kernel triggering the timer upon MAGICCLOSE.
