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.
