1023 : * @keycodesize: size of elements in keycode table
1024 : * @keycode: map of scancodes to keycodes for this device
1025 : * @setkeycode: optional method to alter current keymap, used to implement
1026 : * sparse keymaps. If not supplied default mechanism will be used.
1027 : * The method is being called while holding event_lock and thus must
1028 : * not sleep
1029 : * @getkeycode: optional method to retrieve current keymap. If not supplied
1030 : * default mechanism will be used. The method is being called while
1031 : * holding event_lock and thus must not sleep
1032 : * @ff: force feedback structure associated with the device if device

1051 : * to start generating events (start polling thread,
1052 : * request an IRQ, submit URB, etc.)
1053 : * @close: this method is called when the very last user calls
1054 : * input_close_device().

1056 : * feedback effects loaded into the device when disconnecting
1057 : * from it
1058 : * @event: event handler for events sent _to_ the device, like EV_LED
1059 : * or EV_SND. The device is expected to carry out the requested

1061 : * by @event_lock and must not sleep
1062 : * @grab: input handle that currently has the device grabbed (via

1064 : * recipient for all input events coming from the device

1066 : * and processes a new event for the device (in input_event()).

1068 : * (such as keymap or absmin, absmax, absfuzz, etc.) after device
1069 : * has been registered with input core must take this lock.
1070 : * @mutex: serializes calls to open(), close() and flush() methods
1071 : * @users: stores number of users (input handlers) that opened this
1072 : * device. It is used by input_open_device() and input_close_device()
1073 : * to make sure that dev->open() is only called when the first
1074 : * user opens device and dev->close() is called when the very
1075 : * last user closes the device
1076 : * @going_away: marks devices that are in a middle of unregistering and
1077 : * causes input_open_device*() fail with -ENODEV.
1078 : * @dev: driver model's view of this device
1079 : * @h_list: list of input handles associated with the device. When
