Bisection pointed to:
commit 92045aab1bd9bfd73d816e907ea07739c4550b41 Author: Johannes Berg <johannes.berg@intel.com> Date: Sat Dec 16 05:47:15 2023 +0000
wifi: cfg80211: fix CQM for non-range use commit 7e7efdda6adb385fbdfd6f819d76bc68c923c394 upstream.
Reverting that was not possible, so I reverted 47f3694a4259 first ("wifi: nl80211: fix deadlock in nl80211_set_cqm_rssi (6.6.x)"), but that was not enough. After reverting both 47f3694a4259 and 92045aab1bd9, the build passed again.
Reproducer:
tuxmake --runtime podman --target-arch x86_64 --toolchain gcc-8 --kconfig allmodconfig
Greetings!
