/*
* To write a force-feedback-capable driver, the upload_effect
* and erase_effect callbacks in input_dev must be implemented.
* The uinput driver will generate a fake input event when one of
* these callbacks are invoked. The userspace code then uses
* ioctls to retrieve additional parameters and send the return code.
* The callback blocks until this return code is sent.
*
* The described callback mechanism is only used if ff_effects_max
* is set.
*
* To implement upload_effect():
* 1. Wait for an event with type == EV_UINPUT and code == UI_FF_UPLOAD.
* A request ID will be given in 'value'.
* 2. Allocate a uinput_ff_upload struct, fill in request_id with
* the 'value' from the EV_UINPUT event.
* 3. Issue a UI_BEGIN_FF_UPLOAD ioctl, giving it the
* uinput_ff_upload struct. It will be filled in with the
* ff_effects passed to upload_effect().
* 4. Perform the effect upload, and place a return code back into
the uinput_ff_upload struct.
* 5. Issue a UI_END_FF_UPLOAD ioctl, also giving it the
* uinput_ff_upload_effect struct. This will complete execution
* of our upload_effect() handler.
*
* To implement erase_effect():
* 1. Wait for an event with type == EV_UINPUT and code == UI_FF_ERASE.
* A request ID will be given in 'value'.
* 2. Allocate a uinput_ff_erase struct, fill in request_id with
* the 'value' from the EV_UINPUT event.
* 3. Issue a UI_BEGIN_FF_ERASE ioctl, giving it the
* uinput_ff_erase struct. It will be filled in with the
* effect ID passed to erase_effect().
* 4. Perform the effect erasure, and place a return code back
* into the uinput_ff_erase struct.
* 5. Issue a UI_END_FF_ERASE ioctl, also giving it the
* uinput_ff_erase_effect struct. This will complete execution
* of our erase_effect() handler.

/*
* This is the new event type, used only by uinput.
* 'code' is UI_FF_UPLOAD or UI_FF_ERASE, and 'value'
* is the unique request ID. This number was picked
* arbitrarily, above EV_MAX (since the input system
* never sees it) but in the range of a 16-bit int.
