Subject: [PATCH v2 13/16] DynamicTablesPkg: IORT: Fix uninitialized memory usage
Date: Sun, 29 Mar 2020 16:13:50 +0100 [thread overview]
Message-ID: <20200329151353.14096-14-sami.mujawar@arm.com> (raw)
In-Reply-To: <20200329151353.14096-1-sami.mujawar@arm.com>
On enabling the /analyse option the VS2017 compiler
reports: warning C6001: Using uninitialized memory.
This warning is reported as some variables that were
being logged were uninitialised. To fix this, moved
the logging code after the variables being logged are
initialised.
