6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: Zichen Xie <zichenxie0106@xxxxxxxxx>
[ Upstream commit 13c4f7714c6a1ecf748a2f22099447c14fe6ed8c ]
kunit_kzalloc() may return NULL, dereferencing it without NULL check may
lead to NULL dereference.
Add a NULL check for ies.
Fixes: 45d43937a44c ("wifi: cfg80211: add a kunit test for 6 GHz colocated AP parsing")
