Consequently, all set_mode() implementations in drivers: - can stop modifying tzd's "mode" member, - shall stop taking tzd's lock, as it is taken in the helpers - shall stop calling thermal_zone_device_update() as it is called in the helpers - can assume they are called when the mode truly changes, so checks to verify that can be dropped Not providing set_mode() by a driver no longer prevents the core from being able to set tzd's mode, so the relevant check in mode_store() is removed. Other comments: - acpi/thermal.c: tz->thermal_zone->mode will be updated only after we return from set_mode(), so use function parameter in thermal_set_mode() instead, no need to call acpi_thermal_check() in set_mode() - thermal/imx_thermal.c: regmap writes and mode assignment are done in thermal_zone_device_{en|dis}able() and set_mode() callback - thermal/intel/intel_quark_dts_thermal.c: soc_dts_{en|dis}able() are a part of set_mode() callback, so they don't need to modify tzd->mode, and don't need to fall back to the opposite mode if unsuccessful, as the return value will be propagated to thermal_zone_device_{en|dis}able() and ultimately tzd's member will not be changed in thermal_zone_device_set_mode(). - thermal/of-thermal.c: no need to set zone->mode to DISABLED in of_parse_thermal_zones() as a tzd is kzalloc'ed so mode is DISABLED anyway Signed-off-by: Andrzej Pietrasiewicz [for acerhdf] Acked-by: Peter Kaestle --- drivers/acpi/thermal.c | 21 ++++++----- .../ethernet/mellanox/mlxsw/core_thermal.c | 37 +++++++++---------- drivers/platform/x86/acerhdf.c | 17 +++++---- drivers/thermal/da9062-thermal.c | 6 ++- drivers/thermal/hisi_thermal.c | 6 ++- drivers/thermal/imx_thermal.c | 33 +++++++---------- .../intel/int340x_thermal/int3400_thermal.c | 5 +-- .../thermal/intel/intel_quark_dts_thermal.c | 18 ++------- drivers/thermal/rockchip_thermal.c | 6 ++- drivers/thermal/sprd_thermal.c | 6 ++- drivers/thermal/thermal_core.c | 2 +- drivers/thermal/thermal_of.c | 10 +---- drivers/thermal/thermal_sysfs.c | 11 ++---- 13 files changed, 80 insertions(+), 98 deletions(-) diff --git a/drivers/acpi/thermal.c b/drivers/acpi/thermal.c index 592be97c4456..52b6cda1bcc3 100644 --- a/drivers/acpi/thermal.c +++ b/drivers/acpi/thermal.c @@ -499,7 +499,7 @@ static void acpi_thermal_check(void *data) { struct acpi_thermal *tz = data; - if (tz->thermal_zone->mode != THERMAL_DEVICE_ENABLED) + if (!thermal_zone_device_is_enabled(tz->thermal_zone)) return; thermal_zone_device_update(tz->thermal_zone, @@ -542,14 +542,11 @@ static int thermal_set_mode(struct thermal_zone_device *thermal, if (mode == THERMAL_DEVICE_DISABLED) pr_warn("thermal zone will be disabled\n"); - if (mode != tz->thermal_zone->mode) { - tz->thermal_zone->mode = mode; - ACPI_DEBUG_PRINT((ACPI_DB_INFO, - "%s kernel ACPI thermal control\n", - tz->thermal_zone->mode == THERMAL_DEVICE_ENABLED ?
