I think I already give a strong reason for my decision. Let say that my controller only has space for 4 devices and one of them is offline during pre_assign_dyn_addr() and hence it fails. When device tries to do the HJ I won't be able to do the enumeration because there is no space left. Anyway, you are right and I need to add this to commit message. BTW, It is not clear to me why should we keep non addressed devices allocated when we have i3c_dev_boardinfo list with ->of_node information and what is the problem with allocate/free/re-allocate dance?
