Of course, the patch should have been:

diff --git a/drivers/net/wireless/zd1201.c b/drivers/net/wireless/zd1201.c
index 335eaf3..dcc7bc7 100644
--- a/drivers/net/wireless/zd1201.c
+++ b/drivers/net/wireless/zd1201.c
@@ -1835,6 +1835,8 @@ static int zd1201_probe(struct usb_inter
zd->dev->name);

usb_set_intfdata(interface, zd);
+ zd1201_enable(zd); /* zd1201 likes to startup enabled, interfering */
+ zd1201_disable(zd); /* with all the wifis in range */
return 0;
err_net:


....question is "is that right solution, or is something different
needed to solve that problem properly"?
