1380  *      it may not sleep
1381  * @filter: similar to @event; separates normal event handlers from
1382  *      "filters".
1383  * @match: called after comparing device's id with handler's id_table
1384  *      to perform fine-grained matching between device and handler
1385  * @connect: called when attaching a handler to an input device
1386  * @disconnect: disconnects a handler from input device
1387  * @start: starts handler for given handle. This function is called by
1388  *      input core right after connect() method and also when a process
1389  *      that "grabbed" a device releases it
1390  * @fops: file operations this driver implements
1391  * @minor: beginning of range of 32 minors for devices this driver
1392  *      can provide
1393  * @name: name of the handler, to be shown in /proc/bus/input/handlers
1394  * @id_table: pointer to a table of input_device_ids this driver can
1395  *      handle
1396  * @h_list: list of input handles associated with the handler
1397  * @node: for placing the driver onto input_handler_list

1400  * are likely several handlers attached to any given input device at the
1401  * same time. All of them will get their copy of input event generated by
1402  * the device.
1403  *
1404  * The very same structure is used to implement input filters. Input core
1405  * allows filters to run first and will not pass event to regular handlers
1406  * if any of the filters indicate that the event should be filtered (by
1407  * returning %true from their filter() method).
