Message-ID: <20060801200643.GB22240@redhat.com>

From: Dave Jones <davej@...hat.com>
To: Linux Kernel <linux-kernel@...r.kernel.org>
Subject: 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)
