_named_gpio() could return -ENOENT, -EPROBE_DEFER -EINVAL and so on. Currently, for the optional property "enable-gpio", we only check -EPROBE_DEFER, this is not enough since there may be misconfigured "enable-gpio" in the DTB, of_get_named_gpio() will return -EINVAL in this case, we should return immediately here. And for the optional property "gpios", we didn't check the return value, the driver will continue to the point where gpio_request_array() is called, it doesn't make sense to continue if we got -EPROBE_DEFER or -EINVAL here. This patch tries to address these two issues by properly checking the return value of of_get_named_gpio.
