i2c_verify_client — return parameter as i2c_client, or NULL
struct i2c_client * i2c_verify_client ( | struct device * dev) ; |
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.
