Subject: [PATCH] scsi: storvsc: Remove memset before memory freeing in storvsc_suspend()
Date: Fri, 5 Jun 2020 10:59:34 +0300 [thread overview]
Message-ID: <20200605075934.8403-1-efremov@linux.com> (raw)
In-Reply-To: <CAA42JLat6Ern5_mztmoBX9-ONtmz=gZE3YUphY+njTa+A=efVw@mail.gmail.com>
Remove memset with 0 for stor_device->stor_chns in storvsc_suspend()
before the call to kfree() as the memory contains no sensitive information.
Fixes: 56fb10585934 ("scsi: storvsc: Add the support of hibernation")
