[Question: Drivers/input/evdev.c] What is the use of write function in evdev_fops?

Dear Mr. Torokhov and Linux-Input Community,
Greetings of the day !! :)

I have not seen some good use of write function in input subsystem.
I am trying find the good uses of write function in Input subsystem,
but could not find the solution over internet.
Can you please help in answering my query below:

As you know, in evdev.c file, fops is defined as below
struct file_operations evdev_fops = {
.read           = evdev_read,
.write          = evdev_write,
...
}

So in what cases, evdev_write function is used ?
One case I can think of is that, it can be used in input device simulator
to write the recorded data back into buffer.

Thanks and Regards,
