The variable report is only non-NULL and non-freed in a small region of
code, so it should only be freed in error handling code that comes from
that region.
Thank you for your patch. There isn't a double-kfree though, as far
as I can see.
There was a double free because the error handling at the end of the 
function (for input_register_device) would fall through to the 
kfree(report) under err_free_devs, even though report is already freed at 
that point.
Ah, yes, indeed.. Well, that decides what branch the patch gets
applied then ;)
