commit cb4855b49deb1acce27706ad9509d63c4fe8e988 upstream.
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: 3030d40b5036 ('staging: vt6655: use free_netdev instead of kfree')
Fixes: 0a438d5b381e ('staging: vt6656: use free_netdev instead of kfree')

[wt: only vt6656 was converted to free_netdev in 3.10]
