 * @replay: scheduling of the effect (struct ff_replay)
 * @u: effect-specific structure (one of ff_constant_effect, ff_ramp_effect,
 *      ff_periodic_effect, ff_condition_effect, ff_rumble_effect) further
 *      defining effect parameters
 *
 * This structure is sent through ioctl from the application to the driver.
 * To create a new effect application should set its @id to -1; the kernel
 * will return assigned @id which can later be used to update or delete
 * this effect.
 *
 * Direction of the effect is encoded as follows:
 *      0 deg -> 0x0000 (down)
 *      90 deg -> 0x4000 (left)
 *      180 deg -> 0x8000 (up)
 *      270 deg -> 0xC000 (right)
