SND_SOC_SOF_HDA_PROBES must be tristate because the code it builds depends on code that is tristate. If SND_SOC_SOF_HDA_PROBES is bool it leads to the following build inconsistency: SND_SOC_SOF_HDA_COMMON=m which selects SND_SOC_SOF_HDA_PROBES but since this is a bool SND_SOC_SOF_HDA_PROBES=y SND_SOC_SOF_HDA_PROBES=y selects SND_SOC_SOF_DEBUG_PROBES=y so sof-client-probes.c is built into the kernel. sof-client-probes.c calls functions in sof-client.c, but SND_SOC_SOF=m sof-client.c is built into a loadable module.
