iio: accel: bma220_spi: Do not define 'struct acpi_device_id' when !CONFIG_ACPI
Since ACPI_PTR() is used to NULLify the value when !CONFIG_ACPI, struct 'bma220_acpi_id' becomes defined but unused. Fixes the following W=1 kernel build warning(s): drivers/iio/accel/bma220_spi.c:312:36: warning: ‘bma220_acpi_id’ defined but not used [-Wunused-const-variable=] 312 | static const struct acpi_device_id bma220_acpi_id[] = { | ^~~~~~~~~~~~~~ Cc: Tiberiu Breana <tiberiu.a.breana@intel.com> Signed-off-by: Lee Jones <lee.jones@linaro.org> Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
