Subject: [PATCH 1/9] OvmfPkg: Replace static struct initialization with ZeroMem call
Date: Tue, 21 Mar 2023 19:30:32 -0600 [thread overview]
Message-ID: <20230322013040.3322865-2-rebecca@bsdio.com> (raw)
In-Reply-To: <20230322013040.3322865-1-rebecca@bsdio.com>
Replace the static struct initialization with a call to ZeroMem to avoid
generating a call to memset in certain build configurations.
