I have just sent a fix. The patch I submitted originally did not touch the WM8962_ADDITIONAL_CONTROL_4 register: https://www.spinics.net/lists/alsa-devel/msg112549.html The part that touched this register was below the --- line and it was just a comment, not supposed to get merged. Maybe this confused git. Sorry about that.
