The original series description below is still applicable. This series is part of a larger effort to switch over all drivers using the struct acpi_driver interface to the more common struct platform_driver interface and eliminate the former. The background is explained in Documentation/driver-api/acpi/acpi-drivers.rst and in the changelog of the patch that introduced the above document: https://lore.kernel.org/all/2396510.ElGaqSPkdT@rafael.j.wysocki/ The bottom line is that the kernel would be better off without struct acpi_driver and so it is better to get rid of it. This series carries out driver conversion of the platform x86 Dell Airplane Mode Switch driver. Patch [1/2] updates the driver to install an ACPI notify handler by itself instead of using the .notify() callback from struct acpi_driver, which is requisite for the driver conversion. Patch [2/2] converts the driver to using struct platform_driver for device binding. Thanks!
