 * @abs: current values for reports from absolute axes
 * @rep: current values for autorepeat parameters (delay, rate)

 * @absmin: minimum values for events coming from absolute axes
 * @absfuzz: describes noisiness for axes
 * @absflat: size of the center flat position (used by joydev)
 * @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

 *      from it
 * @event: event handler for events sent _to_ the device, like EV_LED

 *      by @event_lock and must not sleep

 *      recipient for all input events coming from the device
 * @event_lock: this spinlock is is taken when input core receives

 *      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

 * @dev: driver model's view of this device
 * @h_list: list of input handles associated with the device. When
