From 47baf1ad81ed10c158c314ab9f304e674ae32531 Mon Sep 17 00:00:00 2001 From: Tobias Klauser Date: Mon, 13 Mar 2017 12:00:50 +0100 Subject: tty: n_gsm: Use net_device_stats from struct net_device Instead of using a private copy of struct net_device_stats in struct gsm_mux_net, use stats from struct net_device. Also remove the now unnecessary .ndo_get_stats function.
