From 6986df9686c55464b0fa0f36a02f4da81d99a3b1 Mon Sep 17 00:00:00 2001 From: Fuyun Liang Date: Fri, 25 May 2018 19:43:03 +0100 Subject: [PATCH] net: hns3: Removes unnecessary check when clearing TX/RX rings Our code will ensure that hns3_clear_tx_ring is not used to cleared RX rings and hns3_clear_rx_ring is not used to cleared TX rings. So the ring type check is unnecessary.
