+Subject: [PATCH] brcmfmac: fix system warning message during wowl suspend
+
+There is a system warning message, warn_slowpath-fmt, during suspend
+while using supplicant join AP and enable wowl feature by IW command.
+It's caused by brcmf_pno_remove_request path can't find the reqid.
+This fix will not go to remove pno request function if there is no
+pno scan.
