Subject: [PATCH 08/10] iwlwifi: mvm: initialize status in iwl_mvm_add_int_sta_common()
Date: Fri,  8 Sep 2017 12:12:54 +0300	[thread overview]
Message-ID: <20170908091256.25279-9-luca@coelho.fi> (raw)
In-Reply-To: <20170908091256.25279-1-luca@coelho.fi>

From: Luca Coelho <luciano.coelho@intel.com>

We always need to initialize the status argument to the success case
before calling iwl_mvm_send_cmd_status() or
iwl_mvm_send_cmd_pdu_status() (which calls the former) otherwise we
may get an uninitialized value back.  In this case, we use
ADD_STA_SUCCESS as success.

Fixes: 732d06e9d9cf ("iwlwifi: mvm: add station before allocating a queue")
