I2C_VERIFY_CLIENT(9)                 I2C and SMBus Subsystem                 I2C_VERIFY_CLIENT(9)



NAME
       i2c_verify_client - return parameter as i2c_client, or NULL

SYNOPSIS
       struct i2c_client * i2c_verify_client(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_client.
