[bug report] wifi: nl80211: support MLO in auth/assoc

[Dan Carpenter <dan.carpenter@oracle.com>]

Hello Johannes Berg,

This is a semi-automatic email about new static checker warnings.

The patch d648c23024bd: "wifi: nl80211: support MLO in auth/assoc"
from May 31, 2022, leads to the following Smatch complaint:

    net/wireless/mlme.c:328 cfg80211_mlme_assoc()
    warn: variable dereferenced before check 'req->bss' (see line 324)

net/wireless/mlme.c
   323	
   324		err = rdev_assoc(rdev, dev, req);
                                            ^^^
req->bss dereferenced inside the function call

   325		if (!err) {
   326			int link_id;
   327	
   328			if (req->bss) {
                            ^^^^^^^^
Check for NULL is too late

   329				cfg80211_ref_bss(&rdev->wiphy, req->bss);
   330				cfg80211_hold_bss(bss_from_pub(req->bss));

regards,
dan carpenter
