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.
ALSA: pci: depend on ZONE_DMA
There are several sound drivers that 'select ZONE_DMA'. This is
backwards as ZONE_DMA is an architecture capability exported to drivers.
Switch the polarity of the dependency to disable these drivers when the
architecture does not support ZONE_DMA. This was discovered in the
context of testing/enabling devm_memremap_pages() which depends on
ZONE_DEVICE. ZONE_DEVICE in turn depends on !ZONE_DMA.
