	mutex_lock(&chip->mutex);
	r = zd_ioread32v_locked(chip, values, addresses, count);
	mutex_unlock(&chip->mutex);
	return r;
}

Example #2

	                  const zd_addr_t *addr)
{
	int r;
	u32 parts[2];

	r = zd_ioread32v_locked(chip, parts, (const zd_addr_t *)addr, 2);
	if (r) {
		dev_dbg_f(zd_chip_dev(chip),
			"error: couldn't read e2p macs. Error number %d\n", r);
		return r;
	}

	mac_addr[0] = parts[0];
	mac_addr[1] = parts[0] >>  8;
	mac_addr[2] = parts[0] >> 16;
	mac_addr[3] = parts[0] >> 24;
	mac_addr[4] = parts[1];
	mac_addr[5] = parts[1] >>  8;

	return 0;
