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. It is easy to create bug at the such code, and it will be difficult to debug.
soc-dapm has snd_soc_dapm_free() which cleanups debugfs, widgets, list. But, there is no paired initialize function. This patch adds snd_soc_dapm_init() and initilaizing dapm
