From 4d3dd68a1c56674ff666d0622b545992fac31754 Mon Sep 17 00:00:00 2001 From: Martin Blumenstingl Date: Sun, 31 Jul 2022 22:54:52 +0200 Subject: [PATCH 733/768] net: dsa: lantiq_gswip: Use dev_err_probe where appropriate dev_err_probe() can be used to simplify the existing code. Also it means we get rid of the following warning which is seen whenever the PMAC (Ethernet controller which connects to GSWIP's CPU port) has not been probed yet: gswip 1e108000.switch: dsa switch register failed: -517 Signed-off-by: Martin Blumenstingl --- drivers/net/dsa/lantiq_gswip.c | 53 ++++++++++++++++------------------ 1 file changed, 25 insertions(+), 28 deletions(-) --- a/drivers/net/dsa/lantiq_gswip.c +++ b/drivers/net/dsa/lantiq_gswip.c @@ -1919,11 +1919,9 @@ static int gswip_gphy_fw_load(struct gsw msleep(200); ret = request_firmware(&fw, gphy_fw->fw_name, dev); - if (ret) { - dev_err(dev, "failed to load firmware: %s, error: %i\n", - gphy_fw->fw_name, ret); - return ret; - } + if (ret) + return dev_err_probe(dev, ret, "failed to load firmware: %s\n", + gphy_fw->fw_name); /* GPHY cores need the firmware code in a persistent and contiguous * memory area with a 16 kB boundary aligned start address. @@ -1936,9 +1934,9 @@ static int gswip_gphy_fw_load(struct gsw dev_addr = ALIGN(dma_addr, XRX200_GPHY_FW_ALIGN); memcpy(fw_addr, fw->data, fw->size); } else { - dev_err(dev, "failed to alloc firmware memory\n"); release_firmware(fw); - return -ENOMEM; + return dev_err_probe(dev, -ENOMEM, + "failed to alloc firmware memory\n"); } release_firmware(fw); @@ -1965,8 +1963,8 @@ static int gswip_gphy_fw_probe(struct gs gphy_fw->clk_gate = devm_clk_get(dev, gphyname); if (IS_ERR(gphy_fw->clk_gate)) { - dev_err(dev, "Failed to lookup gate clock\n"); - return PTR_ERR(gphy_fw->clk_gate); + return dev_err_probe(dev, PTR_ERR(gphy_fw->clk_gate), + "Failed to lookup gate clock\n"); } ret = of_property_read_u32(gphy_fw_np, "reg", &gphy_fw->fw_addr_offset); @@ -1986,8 +1984,8 @@ static int gswip_gphy_fw_probe(struct gs gphy_fw->fw_name = priv->gphy_fw_name_cfg->ge_firmware_name; break; default: - dev_err(dev, "Unknown GPHY mode %d\n", gphy_mode); - return -EINVAL; + return dev_err_probe(dev, -EINVAL, "Unknown GPHY mode %d\n", + gphy_mode); } gphy_fw->reset = of_reset_control_array_get_exclusive(gphy_fw_np); @@ -2038,8 +2036,9 @@ static int gswip_gphy_fw_list(struct gsw priv->gphy_fw_name_cfg = &xrx200a2x_gphy_data; break; default: - dev_err(dev, "unknown GSWIP version: 0x%x", version); - return -ENOENT; + return dev_err_probe(dev, -ENOENT, + "unknown GSWIP version: 0x%x", + version); } } @@ -2047,10 +2046,9 @@ static int gswip_gphy_fw_list(struct gsw if (match && match->data) priv->gphy_fw_name_cfg = match->data; - if (!priv->gphy_fw_name_cfg) { - dev_err(dev, "GPHY compatible type not supported"); - return -ENOENT; - } + if (!priv->gphy_fw_name_cfg) + return dev_err_probe(dev, -ENOENT, + "GPHY compatible type not supported"); priv->num_gphy_fw = of_get_available_child_count(gphy_fw_list_np); if (!priv->num_gphy_fw) @@ -2150,8 +2148,8 @@ static int gswip_probe(struct platform_d return -EINVAL; break; default: - dev_err(dev, "unknown GSWIP version: 0x%x", version); - return -ENOENT; + return dev_err_probe(dev, -ENOENT, + "unknown GSWIP version: 0x%x", version); } /* bring up the mdio bus */ @@ -2159,10 +2157,9 @@ static int gswip_probe(struct platform_d if (gphy_fw_np) { err = gswip_gphy_fw_list(priv, gphy_fw_np, version); of_node_put(gphy_fw_np); - if (err) { - dev_err(dev, "gphy fw probe failed\n"); - return err; - } + if (err) + return dev_err_probe(dev, err, + "gphy fw probe failed\n"); } /* bring up the mdio bus */ @@ -2170,20 +2167,20 @@ static int gswip_probe(struct platform_d if (mdio_np) { err = gswip_mdio(priv, mdio_np); if (err) { - dev_err(dev, "mdio probe failed\n"); + dev_err_probe(dev, err, "mdio probe failed\n"); goto put_mdio_node; } } err = dsa_register_switch(priv->ds); if (err) { - dev_err(dev, "dsa switch register failed: %i\n", err); + dev_err_probe(dev, err, "dsa switch registration failed\n"); goto mdio_bus; } if (!dsa_is_cpu_port(priv->ds, priv->hw_info->cpu_port)) { - dev_err(dev, "wrong CPU port defined, HW only supports port: %i", - priv->hw_info->cpu_port); - err = -EINVAL; + err = dev_err_probe(dev, -EINVAL, + "wrong CPU port defined, HW only supports port: %i", + priv->hw_info->cpu_port); goto disable_switch; }
