Dmesg log shows "Can not find requested SSID xyz" error message. Currently while preparing scan channel list for firmware Null entries are created for disabled channels. The routine which retrieves this list ignores channels after Null entry. Hence sometimes driver doesn't scan the channel of requested AP and association fails. The issue is fixed by avoiding those NULL entries. Signed-off-by: Amitkumar Karwar Signed-off-by: Bing Zhao Signed-off-by: John W.
