This should be implemented using gpiolib - see WM8962 for an example of
this. That way the control can be plugged into more other subsystems in
the kernel (probably including whenever I or someone else gets around to
it a widget like the one you open code in a later patch). I know some
of the drivers do export the GPIOs using custom APIs but that's
something that should be fixed.

This should've been a separate patch since it's OK to go in as-is.

There's no patch restoring the functionality...

Yes. It's not actually enabling the write sequencer itself, it's
enabling a low rate clock that's shared between a number of functions in
the device including jack detection. Without the clock jack detection
will not function.
