From 20b946ef84961683a7012e84d78f1fad091bb31c Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Thu, 14 Apr 2022 14:04:02 +0200 Subject: [PATCH] nl80211: don't hold RTNL in color change request [ Upstream commit 1b550a0bebfc0b69d6ec08fe6eb58953a8aec48a ] 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.
