If anyone has any objections, please let me know. ------------------ From: Dmitry Antipov [ Upstream commit 1a0d24775cdee2b8dc14bfa4f4418c930ab1ac57 ] In 'cfg80211_scan_6ghz()', an instances of 'struct cfg80211_colocated_ap' are allocated as if they would have 'ssid' as trailing VLA member. Since this is not so, extra IEEE80211_MAX_SSID_LEN bytes are not needed. Briefly tested with KUnit.
