+ * @keycodemax: size of keycode table
+ * @keycodesize: size of elements in keycode table
+ * @keycode: map of scancodes to keycodes for this device
+ * @setkeycode: optional method to alter current keymap, used to implement
+ * sparse keymaps. If not supplied default mechanism will be used.
+ * The method is being called while holding event_lock and thus must
+ * not sleep
+ * @getkeycode: optional method to retrieve current keymap. If not supplied
+ * default mechanism will be used. The method is being called while
+ * holding event_lock and thus must not sleep
+ * @ff: force feedback structure associated with the device if device
+ * supports force feedback effects
+ * @repeat_key: stores key code of the last key pressed; used to implement
+ * software autorepeat
+ * @timer: timer for software autorepeat
+ * @sync: set to 1 when there were no new events since last EV_SYNC
+ * @abs: current values for reports from absolute axes
+ * @rep: current values for autorepeat parameters (delay, rate)
+ * @key: reflects current state of device's keys/buttons
+ * @led: reflects current state of device's LEDs
+ * @snd: reflects current state of sound effects
+ * @sw: reflects current state of device's switches
+ * @absmax: maximum values for events coming from absolute axes

+ * @absfuzz: describes noisiness for axes
+ * @absflat: size of the center flat position (used by joydev)
+ * @absres: resolution used for events coming form absolute axes
+ * @open: this method is called when the very first user calls
+ * input_open_device(). The driver must prepare the device
+ * to start generating events (start polling thread,
+ * request an IRQ, submit URB, etc.)
+ * @close: this method is called when the very last user calls
+ * input_close_device().
+ * @flush: purges the device. Most commonly used to get rid of force
+ * feedback effects loaded into the device when disconnecting
+ * from it
+ * @event: event handler for events sent _to_ the device, like EV_LED
+ * or EV_SND. The device is expected to carry out the requested
+ * action (turn on a LED, play sound, etc.) The call is protected
+ * by @event_lock and must not sleep
+ * @grab: input handle that currently has the device grabbed (via
+ * EVIOCGRAB ioctl). When a handle grabs a device it becomes sole
+ * recipient for all input events coming from the device
+ * @event_lock: this spinlock is is taken when input core receives
+ * and processes a new event for the device (in input_event()).
+ * Code that accesses and/or modifies parameters of a device
+ * (such as keymap or absmin, absmax, absfuzz, etc.) after device
+ * has been registered with input core must take this lock.
+ * @mutex: serializes calls to open(), close() and flush() methods
+ * @users: stores number of users (input handlers) that opened this
+ * device. It is used by input_open_device() and input_close_device()
+ * to make sure that dev->open() is only called when the first
+ * user opens device and dev->close() is called when the very
+ * last user closes the device
+ * @going_away: marks devices that are in a middle of unregistering and
+ * causes input_open_device*() fail with -ENODEV.
+ * @dev: driver model's view of this device
+ * @h_list: list of input handles associated with the device. When
+ * accessing the list dev->mutex must be held
+ * @node: used to place the device onto input_dev_list
