If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 2be4e7fa5c9715f6f75c05b0fc5e621eaac4866c Author: Ajay Singh <ajay.kathat@xxxxxxxxxxxxx> Date: Thu Sep 16 16:49:18 2021 +0000 wilc1000: fix possible memory leak in cfg_scan_result() [ Upstream commit 3c719fed0f3a5e95b1d164609ecc81c4191ade70 ] When the BSS reference holds a valid reference, it is not freed. The 'if' condition is wrong. Instead of the 'if (bss)' check, the 'if (!bss)' check is used. The issue is solved by removing the unnecessary 'if' check because cfg80211_put_bss() already performs the NULL validation.
