Of course I analyzed the whole patch and - as you may have noticed - added
a description for the 3 changes which were made in this patch.
I also know that this first part of the patch changes the scope of the inline

two separate patches from the remaining two changes:
- Fix GPIO Setup of GPIO Port3
- Implement gpio_chip.to_irq
