From: Julia Lawall <Julia.Lawall@xxxxxxx> Delete a variable that is at most only assigned to a constant, but never used otherwise.

A simplified version of the semantic patch that fixes this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ type T; identifier i; constant c; @@ -T i; <... when != i -i = c; ...> // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@xxxxxxx> --- drivers/net/ethernet/micrel/ksz884x.c | 3 --- 1 file changed, 3 deletions(-) diff --git a/drivers/net/ethernet/micrel/ksz884x.c b/drivers/net/ethernet/micrel/ksz884x.c index 8e9dad7..ce84dc2 100644 --- a/drivers/net/ethernet/micrel/ksz884x.c +++ b/drivers/net/ethernet/micrel/ksz884x.c @@ -5853,15 +5853,12 @@ static int netdev_ioctl(struct net_device *dev, struct ifreq *ifr, int cmd) struct dev_info *hw_priv = priv->adapter; struct ksz_hw *hw = &hw_priv->hw; struct ksz_port *port = &priv->port; - int rc; int result = 0; struct mii_ioctl_data *data = if_mii(ifr); if (down_interruptible(&priv->proc_sem)) return -ERESTARTSYS; - /* assume success */ - rc = 0; switch (cmd) { /* Get address of MII PHY in use. */ case SIOCGMIIPHY: -- 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
