Hello Luciano Coelho,
The patch 0ce04ce797f8: "iwlwifi: mvm: set the TX disable bit when
doing a chanctx switch" from May 8, 2014, leads to the following
static checker warning:
drivers/net/wireless/iwlwifi/mvm/mac80211.c:2768
__iwl_mvm_assign_vif_chanctx()
warn: missing error code here? 'iwl_mvm_sta_from_staid_protected()'
failed. 'ret' = '0'
drivers/net/wireless/iwlwifi/mvm/mac80211.c
2761 if (vif->csa_active && vif->type == NL80211_IFTYPE_STATION) {
2762 struct iwl_mvm_sta *mvmsta;
2763
2764 mvmsta = iwl_mvm_sta_from_staid_protected(mvm,
2765
mvmvif->ap_sta_id);
2766
2767 if (WARN_ON(!mvmsta))
2768 goto out;
Did you want to set an error code here? I don't know the code well
enough to say.
2769
2770 /* TODO: only re-enable after the first beacon */
2771 iwl_mvm_sta_modify_disable_tx(mvm, mvmsta, false);
2772 }
2773
2774 goto out;
2775
2776 out_remove_binding:
2777 iwl_mvm_binding_remove_vif(mvm, vif);
2778 iwl_mvm_power_update_mac(mvm);
2779 out:
2780 if (ret)
2781 mvmvif->phy_ctxt = NULL;
2782 return ret;
2783 }
