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.
