Notes: 0) Support for OSSlib post 3.8 was already removed in commit 43a990765a ("sound: Remove OSSlib stuff from linux/soundcard.h"). Five years have passed since that commit: do people still care about OSSlib-3.8? If not, quite a bit of code could be remove from soundcard.h (and probably ultrasound.h). 2) By the way, what is actually meant by: It is no longer possible to actually link against OSSlib with this header, but we still provide these macros for programs using them. Doesn't that mean compatibility to OSSlib isn't even useful? 3) Anyhow, a previous discussion soundcard.h, which led to that commit, starts at https://lkml.org/lkml/2009/1/20/349 . 4) And, yes, I sneaked in a whitespace fix.
