in general, the change should be OK, but neither on zc702 nor zc706 do I
see a difference in respect to deferred probes. With and without the
patch I see:
root@zynq:~# dmesg | grep -i defer
[ 0.097021] zynq-gpio e000a000.gpio: could not find pctldev for node /amba/slcr@f8000000/pinctrl@700/gpio0-default, deferring probe
root@zynq:~#

If you have a case this patch improves things though, feel free to add my
