OK, I think this fix will work for either patch. The problem is that if
the class hasn't been made visible, then the dentry has no inode, so in
that case we can just exit out of sysfs_hash_and_remove().
Someone needs to check this though ... I've ventured further into sysfs
than a sane person ought to go. In fact if I don't leave now, Mr.
Flibble's going to be very cross ...
