Tell handlers about the driver event rate
void input_set_events_per_packet(struct input_dev * dev, int n_events);
dev
the input device used by the driver
n_events
the average number of events between calls to input_sync
If the event rate sent from a device is unusually large, use this function to set the expected event rate. This will allow handlers to set up an appropriate buffer size for the event stream, in order to minimize information loss.
