From: Peter Senna Tschudin <peter.senna@xxxxxxxxx> Convert a nonnegative error return code to a negative one, as returned elsewhere in the function. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> ( if@p1 (\(ret < 0\|ret != 0\)) { ... return ret; } | ret@p1 = 0 ) ... when != ret = e1 when != &ret *if(...) { ... when != ret = e2 when forall return ret; } // </smpl> Signed-off-by: Peter Senna Tschudin <peter.senna@xxxxxxxxx> --- drivers/net/ethernet/dec/tulip/dmfe.c | 12 +++++++++--- 1 file changed, 9 insertions(+), 3 deletions(-) diff --git a/drivers/net/ethernet/dec/tulip/dmfe.c b/drivers/net/ethernet/dec/tulip/dmfe.c index 4d6fe60..d23755e 100644 --- a/drivers/net/ethernet/dec/tulip/dmfe.c +++ b/drivers/net/ethernet/dec/tulip/dmfe.c @@ -446,13 +446,17 @@ static int __devinit dmfe_init_one (struct pci_dev *pdev, /* Allocate Tx/Rx descriptor memory */ db->desc_pool_ptr = pci_alloc_consistent(pdev, sizeof(struct tx_desc) * DESC_ALL_CNT + 0x20, &db->desc_pool_dma_ptr); - if (!db->desc_pool_ptr) + if (!db->desc_pool_ptr) { + err = -ENOMEM; goto err_out_res; + } db->buf_pool_ptr = pci_alloc_consistent(pdev, TX_BUF_ALLOC * TX_DESC_CNT + 4, &db->buf_pool_dma_ptr); - if (!db->buf_pool_ptr) + if (!db->buf_pool_ptr) { + err = -ENOMEM; goto err_out_free_desc; + } db->first_tx_desc = (struct tx_desc *) db->desc_pool_ptr; db->first_tx_desc_dma = db->desc_pool_dma_ptr; @@ -462,8 +466,10 @@ static int __devinit dmfe_init_one (struct pci_dev *pdev, db->chip_id = ent->driver_data; /* IO type range. */ db->ioaddr = pci_iomap(pdev, 0, 0); - if (!db->ioaddr) + if (!db->ioaddr) { + err = -ENOMEM; goto err_out_free_buf; + } db->chip_revision = pdev->revision; db->wol_mode = 0; -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
