From: Randy Dunlap <rdunlap@xxxxxxxxxxxxx> acerhdf uses thermal interfaces so it should depend on THERMAL. It also should not select a thermal driver without checking that THERMAL is enabled. This fixes the following build errors when THERMAL=m and ACERHDF=y. drivers/built-in.o: In function `acerhdf_set_mode': acerhdf.c:(.text+0x3e02e1): undefined reference to `thermal_zone_device_update' drivers/built-in.o: In function `acerhdf_unbind': acerhdf.c:(.text+0x3e052d): undefined reference to `thermal_zone_unbind_cooling_device' drivers/built-in.o: In function `acerhdf_bind': acerhdf.c:(.text+0x3e0593): undefined reference to `thermal_zone_bind_cooling_device' drivers/built-in.o: In function `acerhdf_init': acerhdf.c:(.init.text+0x1c2f5): undefined reference to `thermal_cooling_device_register' acerhdf.c:(.init.text+0x1c360): undefined reference to `thermal_zone_device_register' drivers/built-in.o: In function `acerhdf_unregister_thermal': acerhdf.c:(.text.unlikely+0x3c67): undefined reference to `thermal_cooling_device_unregister' acerhdf.c:(.text.unlikely+0x3c91): undefined reference to `thermal_zone_device_unregister' Signed-off-by: Randy Dunlap <rdunlap@xxxxxxxxxxxxx> Cc: Peter Feuerer <peter@xxxxxxxx> Cc: Darren Hart <dvhart@xxxxxxxxxxxxx> --- drivers/platform/x86/Kconfig | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) --- linux-next-20141215.orig/drivers/platform/x86/Kconfig +++ linux-next-20141215/drivers/platform/x86/Kconfig @@ -38,8 +38,8 @@ config ACER_WMI config ACERHDF tristate "Acer Aspire One temperature and fan driver" + depends on ACPI && THERMAL select THERMAL_GOV_BANG_BANG - depends on ACPI ---help--- This is a driver for Acer Aspire One netbooks.
