A quick follow up on this, since you said you were going to take a look.

I think with the way bluetooth works under Linux, with a bunch of the work
being done in userspace that figuring out if the BT keyboard is paired is
not going to work in kernelspace. So I think the best we can do here is
simply export the angle of the kickstand as an iio angle sensor.
