Subject: [PATCH 02/11] net: ieee802154: ca8210: Stop leaking skb's
Patch-mainline: v5.17-rc3
Git-commit: 621b24b09eb61c63f262da0c9c5f0e93348897e5
References: git-fixes
Upon error the ieee802154_xmit_complete() helper is not called. Only
ieee802154_wake_queue() is called manually. We then leak the skb
structure.
Free the skb structure upon error before returning.
