input_free_device - free memory occupied by input_dev structure
void input_free_device(struct input_dev * dev);
This function should only be used if input_register_device was not called yet or if it failed. Once device was registered use input_unregister_device and memory will be freed once last reference to the device is dropped.
Device should be allocated by input_allocate_device.
If there are references to the input device then memory will not be freed until last reference is dropped.
