From: Arnd Bergmann <arnd@xxxxxxxx> My randconfig build setup ran into a rare build failure with CONFIG_SND_SOC_SOF_INTEL_SOUNDWIRE_LINK_BASELINE=y CONFIG_SND_SOC_SOF_INTEL_SOUNDWIRE=m CONFIG_SOUNDWIRE=y CONFIG_SOUNDWIRE_INTEL=m CONFIG_SND_SOC_SOF_HDA=y CONFIG_SND_SOC_SOF_INTEL_TGL=y x86_64-linux-ld: sound/soc/sof/intel/hda.o: in function `hda_init_caps': hda.c:(.text+0x691): undefined reference to `sdw_intel_cnl_hw_ops' x86_64-linux-ld: hda.c:(.text+0x6f2): undefined reference to `sdw_intel_probe' x86_64-linux-ld: sound/soc/sof/intel/hda.o: in function `hda_sdw_startup': hda.c:(.text+0x1c40): undefined reference to `sdw_intel_startup' x86_64-linux-ld: sound/soc/sof/intel/hda.o: in function `hda_sdw_process_wakeen': hda.c:(.text+0x1cb6): undefined reference to `sdw_intel_process_wakeen_event' x86_64-linux-ld: sound/soc/sof/intel/hda.o: in function `hda_dsp_interrupt_thread': hda.c:(.text+0x1d67): undefined reference to `sdw_intel_thread' x86_64-linux-ld: sound/soc/sof/intel/hda.o: in function `hda_dsp_remove': hda.c:(.text+0x2655): undefined reference to `sdw_intel_exit' My best understanding is that the definition of SND_SOC_SOF_INTEL_SOUNDWIRE_LINK_BASELINE was intended to avoid this problem, but got it wrong for the SND_SOC_SOF_INTEL_SOUNDWIRE=m case, where the 'select' is meant to set SOUNDWIRE_INTEL to the value of SND_SOC_SOF_INTEL_SOUNDWIRE_LINK_BASELINE rather than the intersection of SND_SOC_SOF_INTEL_SOUNDWIRE_LINK_BASELINE and SND_SOC_SOF_INTEL_SOUNDWIRE. Change the condition to check for SND_SOC_SOF_INTEL_SOUNDWIRE to be a boolean rather than a tristate expression in order to propagate this as intended. Signed-off-by: Arnd Bergmann <arnd@xxxxxxxx> --- I could not figure out if this is a recent regression or if the problem has existed for a long time and is just really hard to trigger.
