I take the same idea from 'sound/soc/intel/boards/bytcr_rt5651.c' line 90.

Thanks for pointing that out. It's not my intention. I accidentally removed it. I'll fix this in v3. Chris

On at least one laptop (ECS EF20EA) the 'hp-detect' GPIO is defined in the DSDT table by the ACPI GpioIo resources in _CRS. The GPIO related information should be mapped to the rt5645 driver to enable the jack detection also on non-DT platforms.
