Observing link failure as follows when CONFIG_ACPI is set but both CONFIG_NLS and CONFIG_PCI are unset. drivers/acpi/device_sysfs.o: In function `description_show': device_sysfs.c:(.text+0x48a): undefined reference to `utf16s_to_utf8s' This issue has been previously fxed by 'commit 8a226e00eeed ("PCI: pci-label: Fix build failure when CONFIG_NLS is set to 'm' by allmodconfig")' selecting NLS when ACPI is present. Now that it is possible to have ACPI without PCI, we need an alternative select statement inside the ACPI kconfig.
