Subject: [PATCH 4.14 24/49] staging: rtl8723bs: Fix uninitialized variables
Date: Mon, 14 Jun 2021 12:27:17 +0200 [thread overview]
Message-ID: <20210614102642.659213623@linuxfoundation.org> (raw)
In-Reply-To: <20210614102641.857724541@linuxfoundation.org>
From: Wenli Looi <wlooi@ucalgary.ca>
commit 43c85d770db80cb135f576f8fde6ff1a08e707a4 upstream.
The sinfo.pertid and sinfo.generation variables are not initialized and
it causes a crash when we use this as a wireless access point.
