I do agree, basically.

Allow me to explain more detail that I saw during debug; since the
commit 6e78108bda78 (ASoC: core: Don't probe the component which is
dummy), an exception has been made that dummy component won't be probed,
thus the 'card' passed into soc_probe_component() would not be assigned
to this component. In the other hand, the component struct is initially
created in snd_soc_register_platform() by kzalloc() of platform struct,
its 'card' pointer is remaining an NULL pointer even the widget node
being read.

Perhaps another option is to refine soc_probe_component(), which I have
not dive in.

Sincerely,
Harry
