It is used by input_open_device() and input_close_device() 1139 * to make sure that dev->open() is only called when the first 1140 * user opens device and dev->close() is called when the very 1141 * last user closes the device 1142 * @going_away: marks devices that are in a middle of unregistering and 1143 * causes input_open_device*() fail with -ENODEV. 1144 * @sync: set to %true when there were no new events since last EV_SYN 1145 * @dev: driver model's view of this device 1146 * @h_list: list of input handles associated with the device.
