Matter of style, though I would rather put entire container_of() on
the next line (see for the existing style in the module and use it).

can't be "usb3_port" part derived from the host variable somehow and
to some extend?

Hmm... Can it possible return -EPROBE_DEFER? If so, would it be better
to use other approach to handle it?
