ACPI: Switch back to struct platform_driver::remove()

2024-11-12T20:30:30+00:00

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/acpi 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.

ACPI: AC: Use strscpy() instead of strcpy()

2024-08-26T17:11:58+00:00

Replace strcpy() with strscpy() in the ACPI AC driver. strcpy() has been deprecated because it is generally unsafe, so help to eliminate it from the kernel source.

ACPI: AC: Properly notify powermanagement core about changes

2024-05-28T19:56:40+00:00

The powermanagement core does various actions when a powersupply changes. It calls into notifiers, LED triggers, other power supplies and emits an uevent. To make sure that all these actions happen properly call power_supply_changed().

ACPI: AC: Rename ACPI device from device to adev

2023-10-17T13:43:30+00:00

Since transformation from ACPI driver to platform driver there are two devices on which the driver operates - ACPI device and platform device. For the sake of reader this calls for the distinction in their naming, to avoid confusion. Rename device to adev, as corresponding platform device is called pdev.

ACPI: AC: Replace acpi_driver with platform_driver

2023-10-13T18:11:29+00:00

The AC driver uses struct acpi_driver to register itself while it would be more logically consistent to use struct platform_driver for this purpose, because the corresponding platform device is present and the role of struct acpi_device is to amend the other bus types. ACPI devices are not meant to be used as proper representation of hardware entities, but to collect information on those hardware entities provided by the platform firmware. Use struct platform_driver for registering the AC driver. Suggested-by: Rafael J.

ACPI: bus: Add context argument to acpi_dev_install_notify_handler()

2023-10-06T15:32:51+00:00

Add void *context arrgument to the list of arguments of acpi_dev_install_notify_handler() and modify it to pass that argument as context to acpi_install_notify_handler() instead of its first argument which is problematic in general (for example, if platform drivers used it, they would rather get struct platform_device pointers or pointers to their private data from the context arguments of their notify handlers). Make all of the current callers of acpi_dev_install_notify_handler() take this change into account so as to avoid altering the general functionality.

ACPI: AC: Install Notify() handler directly

2023-07-14T16:58:34+00:00

Modify the ACPI AC driver to install its own Notify() handler directly instead of providing an ACPI driver .notify() callback. This will allow the ACPI driver .notify() callback to be eliminated and it will allow the AC driver to be switched over to a platform one in the future. Suggested-by: Rafael J.
