NAMEi2c_verify_client − return parameter as i2c_client, or NULL

SYNOPSISstruct i2c_client * i2c_verify_client(struct device * dev);

ARGUMENTSdev device, probably from some driver model iterator

DESCRIPTIONWhen traversing the driver model tree, perhaps using driver model iterators like device_for_each_child(), you can´t assume very much about the nodes you find​. Use this function to avoid oopses caused by wrongly treating some non−I2C device as an i2c_client​.
