With CONFIG_ACPI enabled for RISC-V, this driver gets enabled in allmodconfig build. However, RISC-V doesn't support sub-word atomics which is used by this driver and hence allmodconfig build will fail. There is currently no plan to support this driver for RISC-V. So, disable this driver for RISC-V even when ACPI is enabled.
