sound fixes for 4.4-rc1 Here are a collection of small fixes tha have been gathered for 4.4-rc1. The only significant changes are those in PCI drivers Kconfig, to use "depends on" instead of "select" for CONFIG_ZONE_DMA. A reverse select is often more user-friendly, but in this case, it makes hard to manage with the conflict with ZONE_DEVICE, so changed in such a way for now. Others are all small fixes and quirks: an error check in soundcore reigster_chrdev(), HD-audio HDMI/DP phantom jack fix, Intel Broxton DP quirk, USB-audio DSD device quirk, some constifications, etc.
