This is legacy code from an early version of the driver -that supported MIPS based SoCs where the IRQ bits depended on the actual -SoC. As the bits are the same for all ARM based SoC using this driver we -can remove the intermediate variables. - -Signed-off-by: John Crispin <john@phrozen.org> ---- - drivers/net/ethernet/mediatek/mtk_eth_soc.c | 22 ++++++++++------------ - 1 file changed, 10 insertions(+), 12 deletions(-) - ---- a/drivers/net/ethernet/mediatek/mtk_eth_soc.c -+++ b/drivers/net/ethernet/mediatek/mtk_eth_soc.c -@@ -806,7 +806,7 @@ drop: - } - - static int mtk_poll_rx(struct napi_struct *napi, int budget, -- struct mtk_eth *eth, u32 rx_intr) -+ struct mtk_eth *eth) - { - struct mtk_rx_ring *ring = ð->rx_ring; - int idx = ring->calc_idx; -@@ -894,7 +894,7 @@ release_desc: - } - - if (done < budget) -- mtk_w32(eth, rx_intr, MTK_QMTK_INT_STATUS); -+ mtk_w32(eth, MTK_RX_DONE_INT, MTK_QMTK_INT_STATUS); - - return done; - } -@@ -977,28 +977,26 @@ static int mtk_poll_tx(struct mtk_eth *e - static int mtk_poll(struct napi_struct *napi, int budget) - { - struct mtk_eth *eth = container_of(napi, struct mtk_eth, rx_napi); -- u32 status, status2, mask, tx_intr, rx_intr, status_intr; -+ u32 status, status2, mask; - int tx_done, rx_done; - bool tx_again = false; - - status = mtk_r32(eth, MTK_QMTK_INT_STATUS); - status2 = mtk_r32(eth, MTK_INT_STATUS2); -- tx_intr = MTK_TX_DONE_INT; -- rx_intr = MTK_RX_DONE_INT; -- status_intr = (MTK_GDM1_AF | MTK_GDM2_AF); - tx_done = 0; - rx_done = 0; - tx_again = 0; - -- if (status & tx_intr) -+ if (status & MTK_TX_DONE_INT) - tx_done = mtk_poll_tx(eth, budget, &tx_again); - -- if (status & rx_intr) -- rx_done = mtk_poll_rx(napi, budget, eth, rx_intr); -+ if (status & MTK_RX_DONE_INT) -+ rx_done = mtk_poll_rx(napi, budget, eth); - -- if (unlikely(status2 & status_intr)) { -+ if (unlikely(status2 & (MTK_GDM1_AF | MTK_GDM2_AF))) { - mtk_stats_update(eth); -- mtk_w32(eth, status_intr, MTK_INT_STATUS2); -+ mtk_w32(eth, (MTK_GDM1_AF | MTK_GDM2_AF), -+ MTK_INT_STATUS2); - } - - if (unlikely(netif_msg_intr(eth))) { -@@ -1016,7 +1014,7 @@ static int mtk_poll(struct napi_struct * - return budget; - - napi_complete(napi); -- mtk_irq_enable(eth, tx_intr | rx_intr); -+ mtk_irq_enable(eth, MTK_RX_DONE_INT | MTK_RX_DONE_INT); - - return rx_done; - } |
