From: Arnd Bergmann <a...@arndb.de>
The Kconfig logic around SND_SOC_SOF_INTEL_SOUNDWIRE tries to
ensure that all sound modules can be built with the minimal
dependencies, but this fails in some configurations:
x86_64-linux-ld: sound/hda/intel-dsp-config.o: in function
`snd_intel_dsp_driver_probe':
intel-dsp-config.c:(.text+0x134): undefined reference to `sdw_intel_acpi_scan'
Specifically, this happens if the dsp-config driver is built-in but does
not need to use soundwire, while CONFIG_SOUNDWIRE_INTEL is enabled as
a loadable module.
An easier and more correct way to do this is to remove
CONFIG_SND_SOC_SOF_INTEL_SOUNDWIRE_LINK and instead have
the two drivers that can link against SOUNDWIRE_INTEL,
i.e. DSP_CONFIG and SND_SOC_SOF_HDA, select that driver whenever
SND_SOC_SOF_INTEL_SOUNDWIRE_LINK is set.
This however means that SND_SOC_SOF_INTEL_SOUNDWIRE cannot be selected
by users when SOUNDWIRE is only usable by loadable modules and one or
more drivers using SND_SOC_SOF_INTEL_SOUNDWIRE_LINK_BASELINE is built-in.
