First you can add my
Acked-by: Gregory CLEMENT <gregory.clement@xxxxxxxxxxx>

Then as the second patch is a fix, you should add the fix tag: "Fixes:
5715092a458c ("pinctrl: armada-37xx: Add gpio support") " as well as the
'CC: <stable@xxxxxxxxxxxxxxx>" tags.

But your change in the first patch made this second patch more difficult
to backport.

Actually, when I wrote "_update_reg" I was thinking to the update of the
variable, whereas with a function named "_calculate_reg" I am expecting
having the result as a return of the function.

However I am not against your change, as I pointed my main concern is
about the backport of the patch to the stable branch.

Maybe you could change the order of those 2 patches?
