From 31218df77e7f1b9b0a136990a500a7f980e6a573 Mon Sep 17 00:00:00 2001 From: Yizhuo Date: Thu, 29 Aug 2019 21:43:59 -0300 Subject: [PATCH] media: media/pci/ivtv: Variable vbi.type could be uninitialized if macro v4l2_subdev_call set __result an error code Inside function compress_sliced_buf(), variable vbi.type is uninitialized if macro v4l2_subdev_call set __result an error code. However, vbi.type is used in the if statement without any check, which is potentially unsafe.
