Switching this function to AE_CTRL_TERMINATE broke the documented behaviour of acpi_dev_get_resources() - AE_CTRL_TERMINATE does not, in fact, terminate the resource walk because acpi_walk_resource_buffer() ignores it (specifically converting it to AE_OK), referring to that value as "an OK termination by the user function". This means that acpi_dev_get_resources() does not abort processing when the preproc function returns a negative value.
Revert to AE_ABORT_METHOD
