IIUC, the question above came from the point: #if IS_ENABLED(CONFIG_ACPI) && IS_ENABLED(CONFIG_SND_INTEL_NHLT) .... #else .... #endif and here Cezary suggested to drop IS_ENABLED(CONFIG_ACPI) *iff* the dependency can be assured in Kconfig side. But for that assurance, putting "depends on ACPI" in config SND_INTEL_NHLT block won't suffice; that was my followup. So, as of the current code, we can drop IS_ENABLED(CONFIG_ACPI) from the ifdef above, yes. But the dependency is no rock solid at this point, so either some comments or keeping the extra ifdef like the above would be needed, IMO. thanks, Takashi _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx https://mailman.alsa-project.org/mailman/listinfo/alsa-devel
