[PATCH v1 0/3] platform/surface: surfacepro3_button: Use platform device for driver binding

Hi All,

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 Surface Pro3 button
driver.

Patch [1/3] Fixes a wakeup source leak on driver removal.

Patch [2/3] 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 [3/3] converts the driver to using struct platform_driver for device
binding.

Thanks!
