No patience between the v4.16 release candidates eh ;)

commit 6662ae6af82df10259a70c7569b4c12ea7f3ba93
("gpiolib: Keep returning EPROBE_DEFER when we should")

and

commit ce27fb2c56db6ccfe8099343bb4afdab15e77e7b
("gpio: Handle deferred probing in of_find_gpio() properly")

that are both in Torvalds' tree since yesterday should be fixing
this, I think? Did you try just using the upstream HEAD?

Yours,
