FWIW, I tried building a 3.14rc3 kernel with these patches applied and the drivers enabled as modules. On boot on a Dell Venue 8 Pro, all the relevant modules are loaded, but there's no ALSA device, and no obviously useful errors in any logs, or useful output from alsa-info.sh. Is it expected that the driver doesn't actually work yet? Per the recent commits, do I need some kind of firmware? Any debugging that would be useful?
