ACPI: bus: Introduce devm_acpi_install_notify_handler()
Introduce devm_acpi_install_notify_handler() for installing an ACPI
notify handler managed by devres that will be removed automatically on
driver detach.
It installs the notify handler on the device object in the ACPI
namespace that corresponds to the owner device's ACPI companion, if
present (an error is returned if the owner device doesn't have an ACPI
companion).
Currently, there is no way to manually remove the notify handler
installed by it because none of its users brought on subsequently
will need to do that.
