Subject: 4.4 Backport request 4d06dd537f95 cdc_ncm: do not call
 usbnet_link_change from cdc_ncm_bind

Can

4d06dd537f95 cdc_ncm: do not call usbnet_link_change from cdc_ncm_bind

be added to 4.4 stable?  This fixes CVE-2016-3951 [The second half
necessary for a complete fix, 666984c8625 ("usbnet: cleanup after bind()
in probe()"), is already present in 4.4.]

Thanks!
