Name
i2c_verify_adapter —
return parameter as i2c_adapter or NULL
Synopsis
struct i2c_adapter * i2c_verify_adapter ( | 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_adapter.
