Dan Carpenter d103fb6726 hsr: Prevent use after free in prp_create_tagged_frame() ... [ Upstream commit 876f8ab52363f649bcc74072157dfd7adfbabc0d ] The prp_fill_rct() function can fail. In that situation, it frees the skb and returns NULL. Meanwhile on the success path, it returns the original skb. So it's straight forward to fix bug by using the returned value.
