From: Thiraviyam Mariyappan <quic_tmariyap@xxxxxxxxxxx> In tx completion, status desc is obtained from offsetting the address from wbm ring. Having HTT_TX_WBM_COMP_STATUS_OFFSET(8) and reserved 8 bytes in status desc offsets the address twice and read the values from the incorrect address. Hence, remove the HTT_TX_WBM_COMP_STATUS_OFFSET from wbm completion address calculation. Also this patch is applicable for WCN7850.
