[PATCH v1 0/3] hwmon: (acpi_power_meter) Bind the driver to a platform device

["Rafael J. Wysocki" <rafael@kernel.org>]

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 hwmon acpi_power_meter
driver.

Patch [1/3] removes some redundant checks from three functions in the
driver to facilitate subsequent changes.

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.

@Jaroslaw, testing this on your systems where the acpi_power_meter driver
is used would be much appreciated.

Thanks!
