[PATCH] iwlwifi: mvm: initialize status in iwl_mvm_add_int_sta_common()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Luca Coelho <luciano.coelho@xxxxxxxxx>

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")
