1. NAME▲

i2c_verify_adapter - return parameter as i2c_adapter or NULL

2. SYNOPSIS ▲

struct i2c_adapter * i2c_verify_adapter(struct device *  dev );

3. ARGUMENTS ▲

dev
    device, probably from some driver model iterator

4. DESCRIPTION ▲

When traversing the driver model tree, perhaps using driver model iterators like device_for_each_child(), you canAqt 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_adapter.
