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. - -Signed-off-by: Rajkumar Manoharan <rmanohar@qti.qualcomm.com> -Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com> ---- - ---- a/drivers/net/wireless/ath/ath10k/ce.c -+++ b/drivers/net/wireless/ath/ath10k/ce.c -@@ -578,17 +578,13 @@ int ath10k_ce_revoke_recv_next(struct at - * The caller takes responsibility for any necessary locking. - */ - int ath10k_ce_completed_send_next_nolock(struct ath10k_ce_pipe *ce_state, -- void **per_transfer_contextp, -- u32 *bufferp, -- unsigned int *nbytesp, -- unsigned int *transfer_idp) -+ void **per_transfer_contextp) - { - struct ath10k_ce_ring *src_ring = ce_state->src_ring;
