I2C_VERIFY_ADAPTER(9) I2C and SMBus Subsystem I2C_VERIFY_ADAPTER(9)

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.
