1067 * @keycodesize: size of elements in keycode table
1068 * @keycode: map of scancodes to keycodes for this device
1069 * @setkeycode: optional method to alter current keymap, used to implement
1070 *      sparse keymaps. If not supplied default mechanism will be used.
1071 *      The method is being called while holding event_lock and thus must
1072 *      not sleep
1073 * @getkeycode: optional method to retrieve current keymap. If not supplied
1074 *      default mechanism will be used. The method is being called while
1075 *      holding event_lock and thus must not sleep
1076 * @ff: force feedback structure associated with the device if device

1092 * @absres: resolution used for events coming form absolute axes
1093 * @open: this method is called when the very first user calls
1094 *      input_open_device(). The driver must prepare the device
1095 *      to start generating events (start polling thread,
1096 *      request an IRQ, submit URB, etc.)
1097 * @close: this method is called when the very last user calls
1098 *      input_close_device().

1100 *      feedback effects loaded into the device when disconnecting
1101 *      from it
1102 * @event: event handler for events sent _to_ the device, like EV_LED
1103 *      or EV_SND. The device is expected to carry out the requested
1104 *      action (turn on a LED, play sound, etc.) The call is protected
1105 *      by @event_lock and must not sleep
1106 * @grab: input handle that currently has the device grabbed (via
1107 *      EVIOCGRAB ioctl). When a handle grabs a device it becomes sole
1108 *      recipient for all input events coming from the device
1109 * @event_lock: this spinlock is is taken when input core receives
1110 *      and processes a new event for the device (in input_event()).
1111 *      Code that accesses and/or modifies parameters of a device
1112 *      (such as keymap or absmin, absmax, absfuzz, etc.) after device
1113 *      has been registered with input core must take this lock.
1114 * @mutex: serializes calls to open(), close() and flush() methods
1115 * @users: stores number of users (input handlers) that opened this
1116 *      device. It is used by input_open_device() and input_close_device()
1117 *      to make sure that dev->open() is only called when the first
1118 *      user opens device and dev->close() is called when the very
1119 *      last user closes the device
1120 * @going_away: marks devices that are in a middle of unregistering and
1121 *      causes input_open_device*() fail with -ENODEV.
1122 * @dev: driver model's view of this device
1123 * @h_list: list of input handles associated with the device. When
1124 *      accessing the list dev->mutex must be held

1429 * struct ff_device - force-feedback part of an input device
1430 * @upload: Called to upload an new effect into device
1431 * @erase: Called to erase an effect from device
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.
