Subject: [PATCH] Bluetooth: Re-order clearing suspend tasks
Git-commit: 3eec158d5eca7dd455118d9e00568aad2371219f
Patch-mainline: v5.10-rc1
References: git-fixes
Unregister_pm_notifier is a blocking call so suspend tasks should be
cleared beforehand. Otherwise, the notifier will wait for completion
before returning (and we encounter a 2s timeout on resume).
Fixes: 0e9952804ec9c8 (Bluetooth: Clear suspend tasks on unregister)
