* thermal: Switch back to struct platform_driver::remove()Uwe Kleine-König2024-11-131-1/+1
| | | | | | | | | | | | | | | | | 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.

* thermal: dove: Convert to platform remove callback returning voidUwe Kleine-König2023-09-291-4/+2
| | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | All of the remaining callers of thermal_zone_device_register() can use thermal_tripless_zone_device_register(), so make them do so in order to allow the former to be dropped.

* thermal: Remove debug or error messages in get_temp() opsDaniel Lezcano2023-03-031-4/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | Some get_temp() ops implementation are showing an error or a debug message if the reading of the sensor fails. The debug message is already displayed from the call site of this ops. So we can remove it. On the other side, the error should not be displayed because in production that can raise tons of messages. Finally, some drivers are showing a debug message with the temperature, this is also accessible through the trace from the core code in the temperature_update() function. Another benefit is the dev_* messages are accessing the thermal zone device field from the structure, so we encapsulate even more the code by preventing these accesses. Remove those messages.

* thermal/core: Use the thermal zone 'devdata' accessor in thermal located driversDaniel Lezcano2023-03-031-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The thermal zone device structure is exposed to the different drivers and obviously they access the internals while that should be restricted to the core thermal code. In order to self-encapsulate the thermal core code, we need to prevent the drivers accessing directly the thermal zone structure and provide accessor functions to deal with. Use the devdata accessor introduced in the previous patch. No functional changes intended.

* thermal: consistently use int for temperaturesSascha Hauer2015-08-031-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The thermal code uses int, long and unsigned long for temperatures in different places. Using an unsigned type limits the thermal framework to positive temperatures without need. Also several drivers currently will report temperatures near UINT_MAX for temperatures below 0°C. This will probably immediately shut the machine down due to overtemperature if started below 0°C. 'long' is 64bit on several architectures. This is not needed since INT_MAX °mC is above the melting point of all known materials. Consistently use a plain 'int' for temperatures throughout the thermal code and the drivers. This only changes the places in the drivers where the temperature is passed around as pointer, when drivers internally use another type this is not changed.
