3.14-stable review patch. If anyone has any objections, please let me know.
------------------ From: WANG Cong <[email protected]> [ Upstream commit de185ab46cb02df9738b0d898b0c3a89181c5526 ] It is possible that the interface is already gone after joining the list of anycast on this interface as we don't hold a refcount for the device, in this case we are safe to ignore the error. What's more important, for API compatibility we should not change this behavior for applications even if it were correct.
