Subject[PATCH v2 13/14] spi: spi-pxa2xx: Do not define 'struct acpi_device_id' when !CONFIG_ACPI
Date
Since ACPI_PTR() is used to NULLify the value when !CONFIG_ACPI,
struct 'pxa2xx_spi_acpi_match' becomes defined but unused.

Fixes the following W=1 kernel build warning(s):

drivers/spi/spi-pxa2xx.c:1435:36: warning: ‘pxa2xx_spi_acpi_match’ defined but not used [-Wunused-const-variable=]
1435 | static const struct acpi_device_id pxa2xx_spi_acpi_match[] = {
| ^~~~~~~~~~~~~~~~~~~~~
