Please see commit 0f4bccdbbe642fc620d2b70f60c8ddc4ad09a5db ('Refactor
channel list update event in wpa_supplicant'). That dl_list_for_each()
in wpa_supplicant_update_channel_list() would seem to be needed to call
wpas_p2p_update_channel_list() at the end of the updates. The changes
you are proposing in this patch would seem to undo at least parts of
that earlier fix. As such, I'm not really keen on applying this without
much clearer justification on this fixing something. In other words, I'd
much rather use the simpler patch to allow the test cases pass unless
someone can go through all the possible channel list update sequences in
more detail.

Which events are these (other than the channel list change indication)?
