3.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jakub Kicinski <jakub.kicinski@xxxxxxxxx>
commit f01fc1a82c2ee68726b400fadb156bd623b5f2f1 upstream.
ixgbe_notify_dca cannot be called before driver registration
because it expects driver's klist_devices to be allocated and
initialized. While on it make sure debugfs files are removed
when registration fails.
