>From 564f111f196d9d7293e922a68ba973210d191129 Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Wed, 27 Mar 2013 13:59:05 -0400 Subject: [PATCH] yam: remove redundant null check on dev yam_open has a redundant null check on null, it will never be called with dev == NULL. Remove this redundant check. This also cleans up a smatch warning: drivers/net/hamradio/yam.c:869 yam_open() warn: variable dereferenced before check 'dev' (see line 867) Signed-off-by: Colin Ian King --- drivers/net/hamradio/yam.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/net/hamradio/yam.c b/drivers/net/hamradio/yam.c index 4cf8f10..b2d863f 100644 --- a/drivers/net/hamradio/yam.c +++ b/drivers/net/hamradio/yam.c @@ -866,7 +866,7 @@ static int yam_open(struct net_device *dev) printk(KERN_INFO "Trying %s at iobase 0x%lx irq %u\n", dev->name, dev->base_addr, dev->irq); - if (!dev || !yp->bitrate) + if (!yp->bitrate) return -ENXIO; if (!dev->base_addr || dev->base_addr > 0x1000 - YAM_EXTENT || dev->irq < 2 || dev->irq > 15) { -- 1.7.9.5
