From 2aac3388f1682d6208f6759c338a7efa37b0deca Mon Sep 17 00:00:00 2001 From: Matthias Kaehlcke Date: Mon, 26 Jun 2017 17:25:33 -0700 Subject: [PATCH] iio: magnetometer: Only declare ACPI table when ACPI is enable Don't inflate the kernel size with data that isn't used. The conditional declaration also fixes the following warning when building with clang: drivers/iio/magnetometer/ak8975.c:704:36: error: variable 'ak_acpi_match' is not needed and will not be emitted [-Werror,-Wunneeded-internal-declaration] Signed-off-by: Matthias Kaehlcke Acked-by: Linus Walleij Signed-off-by: Jonathan Cameron --- drivers/iio/magnetometer/ak8975.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/drivers/iio/magnetometer/ak8975.c b/drivers/iio/magnetometer/ak8975.c index 825369fb1c57..4ff883942f7b 100644 --- a/drivers/iio/magnetometer/ak8975.c +++ b/drivers/iio/magnetometer/ak8975.c @@ -784,6 +784,7 @@ static const struct iio_info ak8975_info = { .driver_module = THIS_MODULE, }; +#ifdef CONFIG_ACPI static const struct acpi_device_id ak_acpi_match[] = { {"AK8975", AK8975}, {"AK8963", AK8963}, @@ -793,6 +794,7 @@ static const struct acpi_device_id ak_acpi_match[] = { { }, }; MODULE_DEVICE_TABLE(acpi, ak_acpi_match); +#endif static const char *ak8975_match_acpi_device(struct device *dev, enum asahi_compass_chipset *chipset)
