          This enables support for the Philips UCB1400 GPIO pins.
          The UCB1400 is an AC97 audio codec.

          To compile this driver as a module, choose M here: the
          module will be called ucb1400_gpio.

But you use bool above, so choosing M isn't actually an option.
Maybe you want to resolve this inconsistency.
I don't really have any device with ucb1400 available now. I will have
some probably sometimes soon though. On the other hand, if you know
it's a correct fix, you can send a patch.
This note hasn't got much to do with the driver code itself.  Either you
want to enable compiling the driver as a module, then use tristate
instead of bool; or it isn't an option and then remove the corresponding
paragraph from the documentation.  The latter is improbable, and a
quick look at the code seems to confirm that the driver was actually
intended to be used as a module.  So I suggest replacing bool with
tristate.  But I don't know anything at all about this driver or device.

I know what this thing is -- it's a MFD chip with audio/touchscreen/gpio on it. 
I'll get to a device with such thing soon, so don't worry. I'll keep this in 
ToDo. I think it should be possible to compile this as a module btw.
