Since we will remove items off the list using list_del() we need
to use a safe version of the list_for_each() macro aptly named
list_for_each_safe().

Hello, I apologize for prematurely ack'ing this. There is another situation where you could use list_for_each_entry_safe in the function handle_error_info_rsp. Could you include this in your patch, please?
