Thanks for your reviewing and pointing to this function.

No need to recall the devm_pinctrl_get() during the i2c probe, as the 
pinctrl_bind_pins() is enough to init the pinctrl struct. But still need 
to set the rinfo->pinctrl with dev->pins->p, will upload new patchset.

The change will look like:

@@ -832,6 +833,9 @@ static int i2c_dw_init_recovery_info(struct 
dw_i2c_dev *dev)
        struct i2c_adapter *adap = &dev->adapter;
        struct gpio_desc *gpio;

+       if (dev->dev->pins && dev->dev->pins->p)
+               rinfo->pinctrl = dev->dev->pins->p;
+
        gpio = devm_gpiod_get_optional(dev->dev, "scl", GPIOD_OUT_HIGH);
        if (IS_ERR_OR_NULL(gpio))
                return PTR_ERR_OR_ZERO(gpio);

Thanks,
Hanna
