From c3001b773bb63afd403bae37febf3f09826912cb Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Tue, 5 Jun 2012 20:31:29 +0000 Subject: [PATCH] net/ethernet: ks8851_mll unregister_netdev() before freeing We added another error condition here, but if we were to hit it then we need to unregister_netdev() before doing the free_netdev(). Otherwise we would hit the BUG_ON() in free_netdev(): BUG_ON(dev->reg_state != NETREG_UNREGISTERED); Signed-off-by: Dan Carpenter Tested-by: Raffaele Recalcati Signed-off-by: David S.
