Commit b87b49cd0efd ("ACPI / PM: Move device PM functions related to sleep states") declared acpi_target_system_state() for CONFIG_PM_SLEEP whereas it is only defined for CONFIG_ACPI_SLEEP, resulting in the following link error: drivers/built-in.o: In function `acpi_pm_device_sleep_wake': drivers/acpi/device_pm.c:342: undefined reference to `acpi_target_system_state' drivers/built-in.o: In function `acpi_dev_suspend_late': drivers/acpi/device_pm.c:501: undefined reference to `acpi_target_system_state' drivers/built-in.o: In function `acpi_pm_device_sleep_state': drivers/acpi/device_pm.c:221: undefined reference to `acpi_target_system_state' Define it only for CONFIG_ACPI_SLEEP and fallback to a dummy definition for other configs.
