Subject: [PATCH 5.5 19/23] media: dvb-usb/dvb-usb-urb.c: initialize actlen to 0
Date: Mon, 3 Feb 2020 16:20:39 +0000 [thread overview]
Message-ID: <20200203161906.309094277@linuxfoundation.org> (raw)
In-Reply-To: <20200203161902.288335885@linuxfoundation.org>
From: Hans Verkuil <hverkuil-cisco@xs4all.nl>
commit 569bc8d6a6a50acb5fcf07fb10b8d2d461fdbf93 upstream.
This fixes a syzbot failure since actlen could be uninitialized,
but it was still used.
