From: Julia Lawall <redacted> 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 ;) -- Dmitry
