+	if (mdev->registered == 0) {
+		retval = device_register(&mdev->dev);
+		if (retval) {
+			printk(KERN_INFO
+			"Maple bus: Attempt to register device"
+			" (%x, %x) failed.\n",

 }


Specifically the check on mdev->registered

Unfortunately the previous commit was completely corrupted by whitespace
everywhere so the patch essentially covers the whole dirver (I had a
choice of submitting broken code with whitespace removed or working code
with whitespace removed)
