vbus_state is assign with the value of "-1" in davinci.c file.
However it check value whether it is zero or a non-zero.

This value pass On gpio lib function.Which need this value to bool only.

On below "glue->vbus_state" should be 1.

	glue->vbus = devm_gpiod_get_optional(&pdev->dev, NULL, GPIOD_OUT_LOW);
	if (IS_ERR(glue->vbus)) {
                ret = PTR_ERR(glue->vbus);
                goto err0;
        } else {
                glue->vbus_state = -1;
                INIT_WORK(&glue->vbus_work, evm_deferred_drvvbus);
        }
