Subject: [PATCH] nl80211: ignore the length of hide ssid is zero in scan
Date: Thu, 28 Jan 2021 19:56:52 +0800 [thread overview]
Message-ID: <20210128115652.8564-1-samirweng1979@163.com> (raw)
From: wengjianfeng <wengjianfeng@yulong.com>
If the length of hide ssid is zero in scan, don't pass
it to driver, which doesn't make any sense.
