From 209e5ac83b4d038ffb52cabc793f75031602a031 Mon Sep 17 00:00:00 2001 From: Francois Romieu Date: Thu, 26 Jan 2012 09:59:50 +0100 Subject: [PATCH] r8169: remove rtl8169_reinit_task. I see no good reason to keep both rtl8169_reinit_task and rtl8169_reset_task: - rtl8169_reinit_task adds a software failure point which does relate to any hardware state - they handle hardware the same. Remember that rtl8169_reinit_task was introduced in the 8169 only era to handle PCI errors way before the 8168 asked for pll and firmware ops and compare : rtl8169_reinit_task | rtl8169_reset_task ----------------------------+-------------------------- rtl8169_wait_for_quiescence | rtl8169_hw_reset rtl8169_update_counters | rtl8169_wait_for_quiescence rtl8169_hw_reset | rtl_hw_start rtl8169_rx_missed | rtl8169_check_link_status rtl_pll_power_down | rtl_request_firmware | rtl8169_init_phy | rtl_pll_power_up | rtl_hw_start | rtl8169_check_link_status | Signed-off-by: Francois Romieu Cc: Hayes Wang --- drivers/net/ethernet/realtek/r8169.c | 34 +++------------------------- 1 file changed, 3 insertions(+), 31 deletions(-) diff --git a/drivers/net/ethernet/realtek/r8169.c b/drivers/net/ethernet/realtek/r8169.c index ca86e67a33a8..4f0856b8fab3 100644 --- a/drivers/net/ethernet/realtek/r8169.c +++ b/drivers/net/ethernet/realtek/r8169.c @@ -5353,34 +5353,6 @@ static void rtl8169_wait_for_quiescence(struct net_device *dev) napi_enable(&tp->napi); } -static void rtl8169_reinit_task(struct work_struct *work) -{ - struct rtl8169_private *tp = - container_of(work, struct rtl8169_private, task.work); - struct net_device *dev = tp->dev; - int ret; - - rtnl_lock(); - - if (!netif_running(dev)) - goto out_unlock; - - rtl8169_wait_for_quiescence(dev); - rtl8169_close(dev); - - ret = rtl8169_open(dev); - if (unlikely(ret < 0)) { - if (net_ratelimit()) - netif_err(tp, drv, dev, - "reinit failure (status = %d).
