On public Linux lists you should never top post (so people have context and know what you're talking about) and you should fix your mail client to word wrap within paragraphs.

I originally started down the path you are describing, but quickly ran into problems. I started by adding a soc_pcm_copy and soc_pcm_mmap and found that I needed to pull code from ALSA core in to handle the case where copy or mmap was NULL for a given platform driver.

In that case your changelog needs to explain this and I'd still use a function for those ops that don't have stubs in the core. Things like ioctl() could usefully be routed to all the drivers, for example.
