[PATCH] compal-laptop: Variable "value" in function ec_read_u8() could be uninitialized
From: Yizhuo
Date: Mon Sep 02 2019 - 15:52:20 EST
In function ec_read_u8(), variable "value" could be uninitialized
if ec_read() fails. However, "value" is returned directly and used
in its callers. This is potentially unsafe.
