1432  * @playback: Called to request device to start playing specified effect
1433  * @set_gain: Called to set specified gain
1434  * @set_autocenter: Called to auto-center device
1435  * @destroy: called by input core when parent input device is being
1436  *	destroyed
1437  * @private: driver-specific data, will be freed automatically
1438  * @ffbit: bitmap of force feedback capabilities truly supported by
1439  *	device (not emulated like ones in input_dev->ffbit)
1440  * @mutex: mutex for serializing access to the device
1441  * @max_effects: maximum number of effects supported by device
1442  * @effects: pointer to an array of effects currently loaded into device
1443  * @effect_owners: array of effect owners; when file handle owning
1444  *	an effect gets closed the effect is automatically erased
1445  *
1446  * Every force-feedback device must implement upload() and playback()
1447  * methods; erase() is optional. set_gain() and set_autocenter() need
1448  * only be implemented if driver sets up FF_GAIN and FF_AUTOCENTER
1449  * bits.
1450  *
1451  * Note that playback(), set_gain() and set_autocenter() are called with
1452  * dev->event_lock spinlock held and interrupts off and thus may not
1453  * sleep.
