Hello Steffen Kothe, and Bartosz Golaszewski,

I have a board with the Fintek F81966 chip, and noticed that
the GPIO exported in a physical pin wasn't working with the latest
kernel.

The board is a https://www.jetwaycomputer.com/MI24.html

Reading the datasheet and asking for help from Fintek for
a way to make both chips work, I ended up with the patch in the
following email.

Bartosz, I sent it to you because you are listed as maintainer for the GPIO
subsystem.
Steffen, you made the change that bring support to the F81804, so I hope
that you still have a board with the F81804.

I only have a board with the F81966, so I can't test if it still works
with your board after applying the patch.

Despite being a small change, and following the method recommended by the
manufacturer, it would be nice to test this on a real board.

Can you please test this change in your board, Steffen?
If anyone else has a board with F81804, can you please confirm if with
this patch the driver recognizes the right GPIO for your board?

If is there anything that could be improved in the patch, let me know
and I will change it as needed.

Thank you all in advance (and Yu Chen from Fintek for the guidance),
Guilherme Destefani.
