3.19.8-ckt4 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Firo Yang <firogm@gmail.com>
commit 38bd83f04c5e9695011dc5c294e0c4e6a9f9052d upstream.
Since ndev->driver_data is allocated by devm_kzalloc(), we do not
need the inappropriate kfree to free it in driver's remove function.
Freeing will trigger when driver unloads.
