Name
i2c_verify_client —
return parameter as i2c_client, or NULL
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.
