ca8210: Fix unsigned mac_len comparison with zero in ca8210_skb_tx()
[ Upstream commit 748b2f5e ] mac_len is of type unsigned, which can never be less than zero. mac_len = ieee802154_hdr_peek_addrs(skb, &header); if (mac_len < 0) return mac_len; Change this to type int as ieee802154_hdr_peek_addrs() can return negative integers, this is found by static analysis with smatch.
