From: Johannes Berg <johannes@xxxxxxxxxxxxxxxx>
Since IO tracing is usually not needed and
generates a lot of data, separate it into
its own trace system so that we can always
enable iwlwifi:* and not have to worry about
getting too much data. If IO tracing is then
really needed we can enable iwlwifi_io:* in
addition and get that data.
