Just a quick run through the code, so:

- please remove polling support, it is not useful in production;
- why do you need a separate probe work instead of doing what you
  need in elants_probe()
- it is not a good idea to register input device first and then
  allocating memory for MT handling.
- I do not understand why kfifo is needed
- please remove the rest of the custom threads
- you do not need to call input_mt_destroy_slots() explicitly
- use request_firmware() instead of special character device to upload
  firmware.
- please use standard kernel-doc markup.
- consider what attributes are there only for debugging and move them to
  debugfs.
- I find the use of enums in this driver quite unconventional, just
  standard #defines would probably be more straightforward.

Thanks.
