Physically there is a jackset which includes a Headphone and a Jackset Mic pin. The patch add thw two pins with the correct pin name so the DAPM management can find the pin and make the jack detection and event reporting work again. The patch also shut up the following error: rockchip-snd-max98090 sound: ASoC: DAPM unknown pin Headset Jack Signed-off-by: Enric Balletbo i Serra <enric.balletbo@collabora.com> Signed-off-by: Mark Brown <broonie@kernel.org>
