The patch titled
drivers/net: remove superfluous memset
has been removed from the -mm tree. Its filename was
drivers-net-remove-superfluous-memset.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: drivers/net: remove superfluous memset
From: Mariusz Kozlowski <m.kozlowski@xxxxxxxxxx>
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.
