Subject: [PATCH] drivers/net: remove superfluous memset
X-Git-Tag: v3.12-rc1~26468^2~564
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=acb2cc8b20d6cb9e65c1e442d59a2449d8774157;p=kernel%2Fkernel-generic.git

[PATCH] drivers/net: remove superfluous memset

	This patch covers something like this:

dev = alloc_*dev(...
...
priv = netdev_priv(dev);
memset(priv, 0, sizeof(*priv));

The memset() here is superfluous. alloc_netdev() uses kzalloc()
to allocate needed memory so there is no need to zero the priv region
twice.
