Subject: [PATCH] brcmfmac: fix p2p scan abort null pointer exception
|
||
|
|
|
||
|
|
When p2p connection setup is performed without having ever done an
|
||
|
|
escan a null pointer exception can occur. This is because the ifp
|
||
|
|
to abort scanning is taken from escan struct while it was never
|
||
|
|
initialized. Fix this by using the primary ifp for scan abort. The
|
||
|
|
abort should still be performed and all scan related commands are
|
||
|
|
performed on primary ifp.
