Just do not use sleep_on, use wait_event or a manual wait loop.

check the mouse driver sample from Alan Cox:
        linux/Documentation/DocBook/mousedriver.tmpl

The document is slightly outdated:

* do not access current->state directly, use set_current_state.
* do not use MOD_INC_USE_COUNT, set module->owner to THIS_MODULE
instead.
