From: Arnd Bergmann <arnd@xxxxxxxx> A rare randconfig build error happens when this driver is enabled, but nothing else enables NLS support: x86_64-linux-ld: drivers/net/hyperv/rndis_filter.o: in function `rndis_filter_set_device_mac': rndis_filter.c:(.text+0x1536): undefined reference to `utf8s_to_utf16s' This is normally selected by PCI, USB, ACPI, or common file systems. Since the dependency on ACPI is now gone, NLS has to be selected here directly.
