[PATCH 3.16.y-ckt 068/183] iwlwifi: mvm: fix failure path when power_update fails in add_interface

From: Luis Henriques
Date: Fri Mar 06 2015 - 05:47:03 EST


3.16.7-ckt8 -stable review patch. If anyone has any objections, please let me know.

------------------

From: Luciano Coelho <luciano.coelho@xxxxxxxxx>

commit fd66fc1cafd72ddf27dbec3a5e29e99839d1bc84 upstream.

When iwl_mvm_power_update_mac() is called, we have already added the
mac context, so if this call fails we should remove the mac.

Fixes: commit e5e7aa8e2561 ('iwlwifi: mvm: refactor power code')
