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 canīt 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.
