I think this is an updatd version of a previous patch, so it should say
"[PATCH V2]" in the subject, and have a description of the changes you
made between the versions here, below the --- line.

So now, this .invert flag is always set directly based on the GPIO
flags. That's good.
I believe this means you should remove the .invert assignment from
static struct snd_soc_jack_gpio tegra_max98090_hp_jack_gpio too, since
it's always over-written, so doesn't need a default value.
Question: Should we make the same change for DT property
nvidia,mic-det-gpios and value tegra_max98090_mic_jack_gpio.invert?
tegra124-nyan.dts currently says GPIO_ACTIVE_HIGH for both hp-det-gpios
and mic-det-gpios. I don't know if the DT is correct for both of those
(and hence making the same change for the mic-det-gpios would break
Nyan) or not.
