We fixed this to use free_netdev() instead of kfree() but unfortunately free_netdev() doesn't accept NULL pointers. Smatch complains about this, it's not something I discovered through testing. Fixes:3030d40b50
('staging: vt6655: use free_netdev instead of kfree') Fixes:0a438d5b38
('staging: vt6656: use free_netdev instead of kfree') Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
