Merge tag 'tags/sound-sdw-kconfig-fixes' into for-linus
ALSA/ASoC/SOF/SoundWire: fix Kconfig issues In January, Intel kbuild bot and Arnd Bergmann reported multiple issues with randconfig. This patchset builds on Arnd's suggestions to a) expose ACPI and PCI devices in separate modules, while sof-acpi-dev and sof-pci-dev become helpers. This will result in minor changes required for developers/testers, i.e. modprobe snd-sof-pci will no longer result in a probe. The SOF CI was already updated to deal with this module dependency change and introduction of new modules. b) Fix SOF/SoundWire/DSP_config dependencies by moving the code required to detect SoundWire presence in ACPI tables to sound/hda.
