| 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.
