2024-11-13thermal: Switch back to struct platform_driver::remove()Uwe Kleine-König
After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/thermal to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer. On the way make a few whitespace changes to make indention consistent.

2023-09-29thermal: int3403: Convert to platform remove callback returning voidUwe Kleine-König
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

2023-01-27thermal: intel: int340x: Rework updating trip pointsRafael J. Wysocki
It is generally invalid to change the trip point indices after they have been exposed via sysfs. Moreover, the thermal objects in the ACPI namespace cannot go away and appear on the fly. In practice, the only thing that can happen when the INT3403_PERF_TRIP_POINT_CHANGED notification is sent by the platform firmware is a change of the return values of those thermal objects. For this reason, add a special function for updating the trip point temperatures after re-evaluating the respective ACPI thermal objects and change int3403_notify() to invoke it instead of int340x_thermal_read_trips() that would change the trip point indices on errors. Also remove the locking from the latter, because it is only called before registering the thermal zone and it cannot race with the zone's callbacks. Signed-off-by: Rafael J.
