Subject: [PATCH] wifi: cfg80211: Replace a label in
cfg80211_parse_ml_sta_data()
From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sun, 31 Dec 2023 11:22:42 +0100
The kfree() function was called in one case by
the cfg80211_parse_ml_sta_data() function during error handling
even if the passed variable contained a null pointer.
This issue was detected by using the Coccinelle software.
Thus use an other label.
