Subject: [PATCH 5.2 05/20] media: au0828: fix null dereference in error path
Date: Fri, 2 Aug 2019 11:39:59 +0200 [thread overview]
Message-ID: <20190802092058.667994555@linuxfoundation.org> (raw)
In-Reply-To: <20190802092055.131876977@linuxfoundation.org>
From: Sean Young <sean@mess.org>
commit 6d0d1ff9ff21fbb06b867c13a1d41ce8ddcd8230 upstream.
au0828_usb_disconnect() gets the au0828_dev struct via usb_get_intfdata,
so it needs to set up for the error paths.
