Example #3

/**
 * pm8xxx_get_irq_stat - get the status of the irq line
 * @chip: pointer to identify a pmic irq controller
 * @irq: the irq number
 *
 * The pm8xxx gpio and mpp rely on the interrupt block to read
 * the values on their pins. This function is to facilitate reading
 * the status of a gpio or an mpp line. The caller has to convert the
 * gpio number to irq number.
 *
 * RETURNS:
 * an int indicating the value read on that line
