Name

i2c_verify_client — return parameter as i2c_client, or NULL

Synopsis

struct i2c_client * i2c_verify_client (struct device * dev);
 

Arguments

dev

device, probably from some driver model iterator

Description

When 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.
