Whats the page fault you get here? This could be related to your problem.
(please show full oops dump.)
input_unregister_device() already calls kfree(). input_free_device() is
only meant for freeing the data before input_register_device() is
succesfully called. I ran into this same issue while writing ati_remote2
input driver.
