dw_i3c_master_daa() derives the number of newly assigned dynamic addresses from cmd->rx_len, the ISR sets it to the number of address slots ENTDAA left unassigned. It starts out as zero, which already means "every address was assigned", so a timed out transfer leaves that value in place and it gets used as a result. If there's no client connected, the addr assign cmd times out, then the driver calls i3c_master_add_i3c_dev_locked() to add devices that are not there, each costing about 1s, thus adds non necessary boot time up to (maxdev * 1)s. Start from maxdevs instead: no address is assigned before ENTDAA runs, and the existing rx_count >= maxdevs check then reports an empty bus.
