So it's better to leave it as is? Not sure there is good reason to do so, these are internal anyway.

Oops, I had another comment that I deleted accidentally before I submitted. I was just wondering if there's any chance this will be used in an out-of-tree module, or it's entirely internal to the snd infrastructure.

Anyhow I think it doesn't really matter if flags 1/2/4 are unused but I won't object to changing this if it has no external use/visibility.
