/*
 * To write a force-feedback-capable driver, the upload_effect

 * The callback blocks until this return code is sent.
 *
 * The described callback mechanism is only used if ff_effects_max
 * is set.

 *   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
