You are doing the same free twice.
Yes, because it was get twice.
I guess you meant to also free: usb_put_dev(ar->udev)
udev and ar->udev are equal, so technically the patch is correct.
I agree that there is some inconsistency, but I would prefer to fix it
at usb_get_dev() side with a comment about reasons for the double get.
