[ALSA] Fix the soc code after dhowells workqueue changes.
From: Andrew Morton <akpm@osdl.org> I converted the workqueues to per-device while I was there. It seems strange to create a new kernel thread (on each CPU!) and to then only have a single global work to ever be queued upon it. Plus without this, I'd have to use the _NAR stuff, gawd help me. Does that workqueue really need to be per-cpu? Does that workqueue really need to exist? Why not use keventd?
