Hi Marc:

I am not sure if there is some gap.
If we move the variable declaration into that scope, then each error branch has to do the kfree job, like:
if (err) {
dev_err(dev->netdev->dev.parent,
"unable to read %s firmware info (err %d)\n",
pcan_usb_pro.name, err);
kfree(bi);
kfree(fi);
kfree(usb_if);

return err;
}
I am not sure if this looks a little less clear?
Thanks!
