Hi All,
This is an update of
https://lore.kernel.org/linux-acpi/5071411.GXAFRqVoOG@rafael.j.wysocki/
adjusting the probe rollback path.
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!
