Ok. Better luck next time. ;) Speaking of which: should I resend
everything as a whole-in-one patch?

I could also provide a download link (given we're talking 170+kb here)

If've dropped all the new typedefs and only kept the existing ones now.
However, it still reads "enum foo something" in the structs for some
ioctls.

Is this acceptable or do I have to change this to int? If so, would I
manually add a couple of #defines? I somehow feel losing the semantic
connection to the enum is bad, but this might OTOH be intended, e.g. for
the sake of a stable interface.

Cross-checked with hdspmixer and moved to .c, except for the channel
mappings as they're included from userspace. (channel_map*)

It already was for the very last days. But I'm more excited about my new
friend Lindent. ;)
