+Subject: [PATCH] usbnet: fix status interrupt urb handling
+
+Since commit 7b0c5f21f348a66de495868b8df0284e8dfd6bbf
+"sierra_net: keep status interrupt URB active", sierra_net triggers
+status interrupt polling before the net_device is opened (in order to
+properly receive the sync message response).
+
+To be able to receive further interrupts, the interrupt urb needs to be
+re-submitted, so this patch removes the bogus check for netif_running().
