Subject: [PATCH] media: rcar_drif: fix a memory disclosure
Date: Thu, 17 Oct 2019 23:47:00 -0500 [thread overview]
Message-ID: <20191018044701.4786-1-kjlu@umn.edu> (raw)
"f->fmt.sdr.reserved" is uninitialized. As other peer drivers
like msi2500 and airspy do, the fix initializes it to avoid
memory disclosures.
