The parser returns -EPROBE_DEFER for a missing endpoint, which is what a sensor on an ACPI system needs: there the endpoint is a software node that the IPU bridge attaches when the IPU driver probes, possibly after this driver. On OF systems a missing endpoint now defers the probe as well instead of failing it, as in other sensor drivers that leave this check to the parser.
