From 7a6a53b2b1a3e68b69cd75a74783f4d8fd5b6fb5 Mon Sep 17 00:00:00 2001 From: Jeff LaBundy Date: Mon, 25 Jan 2021 10:13:14 -0800 Subject: [PATCH] Input: iqs5xx - initialize an uninitialized variable If execution jumps to the err_kfree label, error_bl is evaluated before it is initialized. Fix this by initializing it to zero.
