I might be out on deep water here, but isn't this racy? Or is azx_firmware_cb somehow guaranteed not to execute before this function has exited?
chip->probe_deferred is used only at the line below. So basically it's not necessarily to be recorded in chip, but could be a local bool variable in azx_probe(). It remains in chip just because of my older patch had it.

Here it's checked.
