-Subject: [PATCH] ath10k: cleanup copy engine send completion
-
-The physical address necessary to unmap DMA ('bufferp') is stored
-in ath10k_skb_cb as 'paddr'. ath10k doesn't rely on the meta/transfer_id
-when handling send completion (htc ep id is stored in sk_buff control
-buffer). So the unused output arguments {bufferp, nbytesp and transfer_idp}
-are removed from CE send completion. This change is needed before removing
-the shadow copy of copy engine (CE) descriptors in follow up patch.
