[34/89] usbnet/cdc_ncm: add missing .reset_resume hook

From: Greg KH
Date: Thu Jun 16 2011 - 03:37:42 EST

2.6.39-stable review patch. If anyone has any objections, please let us know.


From: Stefan Metzmacher <metze@xxxxxxxxx>

commit 85e3c65fa3a1d0542c181510a950a2be7733ff29 upstream.

This avoids messages like this after suspend:

cdc_ncm 2-1.4:1.6: no reset_resume for driver cdc_ncm?
cdc_ncm 2-1.4:1.7: no reset_resume for driver cdc_ncm?
cdc_ncm 2-1.4:1.6: usb0: unregister 'cdc_ncm' usb-0000:00:1d.0-1.4, CDC NCM

This is important for the Ericsson F5521gw GSM/UMTS modem.
Otherwise modemmanager looses the fact that the cdc_ncm and cdc_acm devices
belong together.

The cdc_ether module does the same.
