With CONFIG_ACPI=n, W=1 and -Werror, 0-day reports:

drivers/iio/accel/stk8312.c:644:36: error:
	'stk8312_acpi_id' defined but not used

Apparently STK8312 is not a valid ACPI ID. Remove the ID table
as this is the only entry.  If ACPI support is desired an explicit
of_device_id table should be added (rather than relying on the fallback
to the existing ID table).
