Subject: [PATCH] soc: qcom: initialize local variable
Date: Wed, 19 Aug 2020 11:46:37 -0700 [thread overview]
Message-ID: <20200819184637.15648-1-trix@redhat.com> (raw)
From: Tom Rix <trix@redhat.com>
clang static analysis reports this problem
pdr_interface.c:596:6: warning: Branch condition evaluates
to a garbage value
if (!req.service_path[0])
^~~~~~~~~~~~~~~~~~~~
This check that req.service_path was set in an earlier loop.
However req is a stack variable and its initial value
is undefined.
So initialize req to 0.
Fixes: fbe639b44a82 ("soc: qcom: Introduce Protection Domain Restart helpers")
