It turns out I didnt post that patch yet.
It might not apply cleanly now since I didnt yet update it after
recent changes. Do you want to see it?

No, it took a more drastic approach of replacing all calls to
sdp_buff,sdp_queue,sdp_advt and sdp_iocb functions by list.h macros.

This probably was too big a change: replacing just the list traversal
functions and the casts with list_for_each and container_of calls
would likely work better.
