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().
-- linux/drivers/base/core.c -- int device_register(struct device *dev) { device_initialize(dev); return device_add(dev); }
device_initialize() is doing each dev member's initialization only, not related to device parent/release/groups. Thus, we can postpone it. let's use device_register() instead of device_initialize()/device_add().
