From d643c432223270844c4fd8dcfaec85404d36bde7 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Thu, 7 May 2015 14:47:50 +0200 Subject: [PATCH] iwlwifi: mvm: handle device start failure correctly If the device fails to start correctly prior to loading the regular runtime firmware (after having run the INIT firmware), treat that error correctly by actually checking the return value of _iwl_trans_start_hw() and stopping the device again before returning an error.
