Sorry for not running checkpatch.pl - I simply forgot it. I applied your suggestion and fixed all warnings, so the patch should be ready now. It's now also diff'ed against the latest snapshot.

This patch adds support for MacBook 3,1 sound by adding a model new "mb31" with the appropriate init verbs, mixers and channel modes to the ALC883 configuration. patch_alc882() and patch_alc883() are modified to handle the MacBook 3,1 sound-chip (Realtek ALC889A) correctly.
