wifi: nxp: add nxpwifi driver for IW61x

Hello Jeff Chen,

Commit 73b01e57ed3e ("wifi: nxp: add nxpwifi driver for IW61x") from Jun 5, 2026 (linux-next), leads to the following Smatch static checker warning:

	drivers/net/wireless/nxp/nxpwifi/cfg80211.c:850 nxpwifi_change_vif_to_sta()
	warn: duplicate check 'ret' (previous on line 840)

    816 static int

    820                           struct vif_params *params)
    821 {
    822         struct nxpwifi_private *priv;
    823         struct nxpwifi_adapter *adapter;
    824         int ret;
    825 
    826         priv = nxpwifi_netdev_get_priv(dev);
    827 
    828         if (!priv)
    829                 return -EINVAL;
    830 
    831         adapter = priv->adapter;
    832 
    833         nxpwifi_dbg(adapter, INFO,
    834                     "%s: changing role to station\n", dev->name);
    835 
    836         ret = nxpwifi_deinit_priv_params(priv);
    837         if (ret)
    838                 goto done;
    839         ret = nxpwifi_init_new_priv_params(priv, dev, type);
    840         if (ret)
    841                 goto done;
    842 
    843         update_vif_type_counter(adapter, curr_iftype, -1);
    844         update_vif_type_counter(adapter, type, 1);
    845         dev->ieee80211_ptr->iftype = type;
    846 
    847         if (nxpwifi_set_bss_mode(priv))
    848                 return -1;

Was this supposed to be?

	ret = nxpwifi_set_bss_mode(priv);

    849 
--> 850         if (ret)
    851                 goto done;

Dead code.

    852 
    853         ret = nxpwifi_sta_init_cmd(priv, false, false);
    854 
    855 done:
    856         return ret;
    857 }
