RE: [PATCH] x86, mce: Print warning if MCE handler fails toregister /dev/mcelog

[Luck, Tony]

-	misc_register(&mce_chrdev_device);
+	if (misc_register(&mce_chrdev_device) != 0)
+		pr_warn("Failed to register mcelog device\n");

Did this actually happen to you?  Or is this just "good practice" to check the
return value from misc_register?

If this can really happen, we should remember that it failed and
just drop out of mce_log() early (no point in queueing up records
when there is no way for a user to ever access them).
