It is easy to read code if it is cleanly using paired function/naming, like start <-> stop, register <-> unregister, etc, etc. But, current ALSA SoC code is very random, unbalance, not paired, etc.
soc-core.c is using device_unregiser(), but there is no its paired device_regiser(). We can find its code at soc_post_component_init() which is using device_initialize() and device_add(). Here, device_initialize() + device_add() = device_register().
device_initialize() is doing each dev member's initialization only. So, the timing is not important here. let's use device_register() instead of device_initialize()/device_add().
