Subject: [PATCH] cfg80211: fix dfs channels remain DFS_AVAILABLE after ch_switch
Git-commit: d34990bbc25559fa1af5e23759c65a3951cbc956
Patch-mainline: v5.4-rc1
References: jsc#SLE-13430
Depending on the regulatory domain, leaving a DFS channel requires
a new CAC to be performed when returning back to that channel.
If needed, update dfs states after a driver channel switch.
