This command is a synchronous call. When the command response comes back we have started/joined it successfully, otherwise an error code will be returned. However, we are still inside .join_ibss handler at this moment. Calling cfg80211_ibss_joined() gives us the warning because ssid_len hasn't been set by cfg80211 yet. Anyway, we will look for other solution to resolve the kernel warning. Hi John, Please drop this patch.
