This looks wrong. The n in nDET in the end of the name of the GPIO line
means active low does it not?

What I usually do when I see this is to properly set it to
GPIO_ACTIVE_LOW in the descriptor table, then invert the logic
where it's getting used.

Also rename to earphone-det instead of -ndet

Thanks for taking a look! I changed it now, but I don't know if
I got the correct number of inversions in the end. How does this look?

Looks wrong, you can just invert the argument to any statement of set_value()
after tagging respective line as active low. Then gpilob will do a second
inversion.

So those two have switched polarity.

Thus drop one ! in front of the expression, just !SND_SOC_DAPM_EVENT_ON(event)

Ok, done. But I still leave the extra 'invert=1' in hs_jack_pin[], right?

These initial values don't seem to be set in the old code you could
just use GPIOD_ASIS as flag to make sure the new code behaves
the same.

Ok.
