Subject: [PATCH] nl80211: don't hold RTNL in color change request
Git-commit: 1b550a0bebfc0b69d6ec08fe6eb58953a8aec48a
Patch-mainline: v5.19-rc1
References: git-fixes
It's not necessary to hold the RTNL across color change
requests, since all the inner locking needs only the
wiphy mutex which we already hold as well.
Fixes: 0d2ab3aea50b ("nl80211: add support for BSS coloring")
