From 0fb68ce02ae73626a61b8d03eab1625021057af5 Mon Sep 17 00:00:00 2001 From: Yizhuo Date: Mon, 26 Aug 2019 20:55:28 -0300 Subject: media: pvrusb2: qctrl.flag will be uninitlaized if cx2341x_ctrl_query() returns error code Inside function ctrl_cx2341x_getv4lflags(), qctrl.flag will be uninitlaized if cx2341x_ctrl_query() returns -EINVAL. However, it will be used in the later if statement, which is potentially unsafe.
