And then in the function thermal_zone_device_register() { ... if (tzp) thermal_zone_set_mode(tzp->mode); ... } The important thing is to prevent exporting the functions thermal_zone_device_enable / disable, so they stay in the thermal framework internals, thus forcing to centralize the control of the thermal zones from the framework and not from the device drivers. Temporarly, until the polling is disabled for disabled thermal zones, the acpi driver can stay in the state it is. It may need special attention afterwards. But I believe setting the mode from the register function will help to clean up a lot of drivers. > --- > drivers/acpi/thermal.c | 48 +++++++++---------- > .../ethernet/mellanox/mlxsw/core_thermal.c | 35 ++------------ > drivers/platform/x86/acerhdf.c | 24 ++++------ > drivers/thermal/da9062-thermal.c | 12 +---- > drivers/thermal/imx_thermal.c | 30 +++++------- > .../intel/int340x_thermal/int3400_thermal.c | 34 +++++-------- > .../thermal/intel/intel_quark_dts_thermal.c | 22 +++------ > drivers/thermal/of-thermal.c | 19 ++------ > 8 files changed, 71 insertions(+), 153 deletions(-) > > diff --git a/drivers/acpi/thermal.c b/drivers/acpi/thermal.c > index 328b479ce7f6..755f12b76c20 100644 > --- a/drivers/acpi/thermal.c > +++ b/drivers/acpi/thermal.c > @@ -172,7 +172,6 @@ struct acpi_thermal { > struct acpi_thermal_trips trips; > struct acpi_handle_list devices; > struct thermal_zone_device *thermal_zone; > - int tz_enabled; > int kelvin_offset; /* in millidegrees */ > struct work_struct thermal_check_work; > }; > @@ -499,8 +498,14 @@ static int acpi_thermal_get_trip_points(struct acpi_thermal *tz) > static void acpi_thermal_check(void *data) > { > struct acpi_thermal *tz = data; > + enum thermal_device_mode mode; > > - if (!tz->tz_enabled) > + /* > + * this driver does not provide ->get_mode(), so calling > + * thermal_zone_device_get_mode() always succeeds > + */ > + thermal_zone_device_get_mode(tz->thermal_zone, &mode); > + if (mode != THERMAL_DEVICE_ENABLED) > return; > > thermal_zone_device_update(tz->thermal_zone, > @@ -526,39 +531,33 @@ static int thermal_get_temp(struct thermal_zone_device *thermal, int *temp) > return 0; > } > > -static int thermal_get_mode(struct thermal_zone_device *thermal, > - enum thermal_device_mode *mode) > -{ > - struct acpi_thermal *tz = thermal->devdata; > - > - *mode = tz->tz_enabled ?
