Yeah. This is a false positive. The free_netdev() is recorded correctly in the database drivers/net/ethernet/cirrus/ep93xx_eth.c | ep93xx_eth_remove | 302 | | RELEASE | 0 | $->dev.driver_data | | But smatch_ssa.c is not tracking that calling free_netdev(pdev->dev.driver_data) and free_netdev(dev) is the same. regards, dan carpenter
