| |
Currently i2c_del_adapter() returns -EINVAL when it gets an adapter which is not registered. But none of the users of i2c_del_adapter() depend on this behavior, so for the sake of being able to sanitize the return type of i2c_del_adapter argue, that the purpose of i2c_del_adapter() is to remove an I2C adapter from the system. If the adapter is not registered in the first place this becomes a no-op. So we can return success without having to do anything.
