From 6c04a515085e6b94266db3e0e05c2700eeffa469 Mon Sep 17 00:00:00 2001 From: Leonardo Potenza Date: Mon, 4 Feb 2008 23:47:16 -0800 Subject: [PATCH] drivers/net/tlan.c: compilation warning fix Add a check for the pci_register_driver() return value. Removed unused variable pad_allocated. The aim of this patch is to remove the following warning messages: drivers/net/tlan.c: In function 'tlan_probe': drivers/net/tlan.c:486: warning: ignoring return value of 'pci_register_driver', declared with attribute warn_unused_result Signed-off-by: Leonardo Potenza Signed-off-by: Andrew Morton Signed-off-by: Jeff Garzik --- drivers/net/tlan.c | 25 ++++++++++++++++++------- 1 file changed, 18 insertions(+), 7 deletions(-) diff --git a/drivers/net/tlan.c b/drivers/net/tlan.c index c99ce74a7a..3af5b92b48 100644 --- a/drivers/net/tlan.c +++ b/drivers/net/tlan.c @@ -465,7 +465,7 @@ static struct pci_driver tlan_driver = { static int __init tlan_probe(void) { - static int pad_allocated; + int rc = -ENODEV; printk(KERN_INFO "%s", tlan_banner); @@ -473,17 +473,22 @@ static int __init tlan_probe(void) if (TLanPadBuffer == NULL) { printk(KERN_ERR "TLAN: Could not allocate memory for pad buffer.\n"); - return -ENOMEM; + rc = -ENOMEM; + goto err_out; } memset(TLanPadBuffer, 0, TLAN_MIN_FRAME_SIZE); - pad_allocated = 1; TLAN_DBG(TLAN_DEBUG_PROBE, "Starting PCI Probe....\n"); /* Use new style PCI probing.
