The branch stable/13 has been updated by bz: URL: https://cgit.FreeBSD.org/src/commit/?id=8c90bf16bc2c6a95701a847820a5101c7125d0fe commit 8c90bf16bc2c6a95701a847820a5101c7125d0fe Author: Bjoern A. Zeeb <bz@FreeBSD.org> AuthorDate: 2021-11-24 17:36:48 +0000 Commit: Bjoern A. Zeeb <bz@FreeBSD.org> CommitDate: 2021-12-30 18:24:37 +0000 net80211: fix -Wunused-but-set-variable warnings Put the offending variables under the appropriate #ifdefs (mostly IEEE80211_DEBUG, in one case IEEE80211_SUPPORT_SUPERG, and in two cases under __notyet__ to revisit why these had been left there but not used).
