Typically I have applied the patch adding gpio_[un]lock_as_irq()
and it conflicts with this. And it requires adding gpiod_* accessors
for these functions too...

Would you mind rebasing this on top of my "devel" branch?

Sorry for the moving target, but after this I think we are ready to
merge the gpiod* interface.
