This patch adds alternative way to specify DAI links by using ACPI names. ACPI name here is considered to be used as an alias for device name during DAI link binding time.
What's DAI?
It comes from Digital Audio Interface, and DAI link in ALSA SoC basically ties together platform, DAI and codec devices by name or device tree node.
+#if IS_ENABLED(CONFIG_ACPI) That's not necessary, because ACPI_HANDLE() is defined as false for CONFIG_ACPI unset.
Actually problem acpi_bus_get_device() that is not available if CONFIG_ACPI is not set. Which suggests was it even meant to be used in drivers that are build for non ACPI systems too?
No, acpi_bus_get_device() shoudn't be used if CONFIG_ACPI is not set.
Thanks!
