mac80211: backport bss color collision work patch
From 9288188438d85e22c23cfd6657ee8a801babc83c Mon Sep 17 00:00:00 2001 From: Lorenzo Bianconi lorenzo@kernel.org Date: Wed, 25 Jan 2023 12:01:02 +0100 Subject: wifi: mac80211: move color collision detection report in a delayed work
Move color collision report in a dedicated delayed work and do not run it in interrupt context in order to rate-limit the number of events reported to userspace. Moreover grab wdev mutex in ieee80211_color_collision_detection_work routine since it is required by cfg80211_obss_color_collision_notify().
