TODO
----
Get the memrar driver cleaned up and upstream (dependency blocking SST)
Replace long/short press with two virtual buttons
Review the printks and kill off any left over ST_ERR: messages
Review the misc device ioctls for 32/64bit safety and sanity
Review the misc device ioctls for size safety depending on config and decide
if space/unused areas should be left
What the sound folks turn up on full review
Using the ALSA frameworks properly
