Although we're mixing bool/int on line 417 and 637 as well, with:

	val |= pin->disable;

and

	pin->disable = val & BIT(0);

respectively. The latter could be dealt with using !!(val & BIT(0)); I
guess the appropriate for for the prior is:

	if (pin->disable)
		val |= BIT(0);

If you would like to update your patch with these as well I'd be happy
to review this.

Thanks,
Bjorn

I would opt for a respin with the above when we are anyways at it,
no hurry as it is no regression anyway.
