Hi Folks, This series reworks the two ACPI button drivers to install notify or fixed event handlers (depending on the device type) by themselves, so the core code need not take the "fixed event handler for a button driver" case in the general driver notify handler installer. As a bonus, it separates the notify handler in the "generic" button driver into a lid notify handler and a proper button notify handler. It modifies also the core to drop the "fixed event handler for a button driver" case from there (last patch). It works for me, but I would appreciate as much testing of this as possible especially on old hardware. Obviously, it replaces https://lore.kernel.org/linux-acpi/4500594.LvFx2qVVIh@kreacher/T/#m064d4130b57cbcb0ece1bb415fae1465ebc20f42 and its followers to some extent, but I think that it's better to deal with the special case first and then take care of the rest. Thanks!
