Subject: [PATCH v1 13/19] DynamicTablesPkg: IORT: Fix uninitialized memory usage
Date: Fri, 23 Aug 2019 11:55:33 +0100	[thread overview]
Message-ID: <20190823105539.13260-14-sami.mujawar@arm.com> (raw)
In-Reply-To: <20190823105539.13260-1-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.
