From 349f6c5c5d827db909a69e5b9e844e8623c8e881 Mon Sep 17 00:00:00 2001 From: Dmitry Artamonow Date: Thu, 28 Oct 2010 10:31:58 -0700 Subject: [PATCH] USB: gadget: fix ethernet gadget crash in gether_setup Crash is triggered by commit e6484930d7 ("net: allocate tx queues in register_netdevice"), which moved tx netqueue creation into register_netdev. So now calling netif_stop_queue() before register_netdev causes an oops. Move netif_stop_queue() after net device registration to fix crash. Signed-off-by: Dmitry Artamonow Signed-off-by: David S.
