[46/74] ixgbe: fix registration order of driver and DCA nofitication

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



3.2.43-rc1 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.
