[PATCH v2] ALSA: aoa: make remove callback of soundbus driver void returned

[Dawei Li]

Since commit fc7a6209d571 ("bus: Make remove callback return void")
forces bus_type::remove be void-returned, it doesn't make much sense
for any bus based driver implementing remove callbalk to return
non-void to its caller.

As such, change the remove function for soundbus based drivers to
return void.
