This patch fixes the error "ravb 11c20000.ethernet eth0: failed to switch device to config mode" during unbind. We are doing register access after pm_runtime_put_sync(). We usually do cleanup in reverse order of init. Currently in remove(), the "pm_runtime_put_sync" is not in reverse order. Probe reset_control_deassert(rstc); pm_runtime_enable(&pdev->dev); pm_runtime_get_sync(&pdev->dev); remove pm_runtime_put_sync(&pdev->dev); unregister_netdev(ndev); .. ravb_mdio_release(priv); pm_runtime_disable(&pdev->dev); Consider the call to unregister_netdev() unregister_netdev->unregister_netdevice_queue->rollback_registered_many that calls the below functions which access the registers after pm_runtime_put_sync() 1) ravb_get_stats 2) ravb_close Fixes: c156633f1353 ("Renesas Ethernet AVB driver proper") Cc: stable@xxxxxxxxxxxxxxx Signed-off-by: Biju Das <biju.das.jz@xxxxxxxxxxxxxx> Reviewed-by: Leon Romanovsky <leonro@xxxxxxxxxx> Link: https://lore.kernel.org/r/20221214105118.2495313-1-biju.das.jz@xxxxxxxxxxxxxx Signed-off-by: Paolo Abeni <pabeni@xxxxxxxxxx> Signed-off-by: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx> --- drivers/net/ethernet/renesas/ravb_main.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) --- a/drivers/net/ethernet/renesas/ravb_main.c +++ b/drivers/net/ethernet/renesas/ravb_main.c @@ -2903,12 +2903,12 @@ static int ravb_remove(struct platform_d priv->desc_bat_dma); /* Set reset mode */ ravb_write(ndev, CCC_OPC_RESET, CCC); - pm_runtime_put_sync(&pdev->dev); unregister_netdev(ndev); if (info->nc_queues) netif_napi_del(&priv->napi[RAVB_NC]); netif_napi_del(&priv->napi[RAVB_BE]); ravb_mdio_release(priv); + pm_runtime_put_sync(&pdev->dev); pm_runtime_disable(&pdev->dev); reset_control_assert(priv->rstc); free_netdev(ndev); Patches currently in stable-queue which might be from biju.das.jz@xxxxxxxxxxxxxx are queue-6.1/ravb-fix-failed-to-switch-device-to-config-mode-message-during-unbind.patch
