[PATCH v2 0/4] platform/x86: panasonic-laptop: Bind to a platform device instead of an ACPI one

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

Hi All,

This is an update of

https://lore.kernel.org/linux-acpi/3616223.QJadu78ljV@rafael.j.wysocki/

adding one patch and updating one patch to fix the driver removal
code ordering.

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 Panasonic
hotkey and LCD brightness control driver.

Patch [1/4] fixes the rollback path in acpi_pcc_hotkey_add() and rearranges
the driver removal code ordering to match it.

Patch [2/4] removes some redundant checks from the driver.

Patch [3/4] 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 [4/4] converts the driver to using struct platform_driver for device
binding.

Thanks!
