+ * struct input_handler - implements one of interfaces for input devices
+ * @private: driver-specific data
+ * @event: event handler
+ * @connect: called when attaching a handler to an input device
+ * @disconnect: disconnects a handler from input device
+ * @start: starts handler for given handle. This function is called by
+ *	input core right after connect() method and also when a process
+ *	that "grabbed" a device releases it
+ * @fops: file operations this driver implements
+ * @minor: beginning of range of 32 minors for devices this driver
+ *	can provide
+ * @name: name of the handler, to be shown in /proc/bus/input/handlers
+ * @id_table: pointer to a table of input_device_ids this driver can
+ *	handle
+ * @blacklist: prointer to a table of input_device_ids this driver should
+ *	ignore even if they match @id_table
+ * @h_list: list of input handles associated with the handler
+ * @node: for placing the driver onto input_handler_list
