[WATCHDOG] improve machzwd detection

On a machine with no machzwd, loading the module prints out.. machzwd: MachZ ZF-Logic Watchdog driver initializing. 0xffff machzwd: Watchdog using action = RESET - the 0xffff printk is unnecessary - 0xffff seems to be 'hardware not present' - fix CodingStyle. (This driver could use some more work here) Signed-off-by: Dave Jones <[email protected]> Signed-off-by: Wim Van Sebroeck <[email protected]> Signed-off-by: Andrew Morton <[email protected]>
