But your patch doesn't do this cleanly, it breaks all usages of JD1 that relied on the previous default. Changing the default for jack detection also doesn't really decrease the need for quirks in itself, for this we would need to handle the RT715 quirk and also fix the amplifier link id, and also set the HDMI quirk depending on the platform setting. Bard's working on this, see https://github.com/thesofproject/linux/pull/3203
