Just include a hunk to the qcom driver reordering this call
at the same time. No need to make it separate patches,
it need to be tested together anyways.

I guess just switch the order of these two:

        ret = gpiochip_add_data(&pctrl->chip, pctrl);
        if (ret) {
                dev_err(pctrl->dev, "Failed register gpiochip\n");
                return ret;
        }

        ret = msm_gpio_init_valid_mask(chip, pctrl);
        if (ret) {
                dev_err(pctrl->dev, "Failed to setup irq valid bits\n");
                gpiochip_remove(&pctrl->chip);
                return ret;
        }

Don't think so.
