Do you mean that I should use #ifdef CONFIG_ACPI and ACPI_PTR?
#ifdef CONFIG_ACPI
static const struct acpi_device_id goodix_acpi_match[] = {
{ "GDIX1001", 0 },
{ }
};
MODULE_DEVICE_TABLE(acpi, goodix_acpi_match);
#endif
#ifdef CONFIG_OF
static struct of_device_id goodix_of_match[] = {
{ .compatible = "goodix,gt9xx" },
{ }
};
MODULE_DEVICE_TABLE(of, goodix_of_match);
#endif
static struct i2c_driver goodix_ts_driver = {
...
.acpi_match_table = ACPI_PTR(goodix_acpi_match),
.of_match_table = of_match_ptr(goodix_of_match),
}
