Subject: [PATCH 1/1] ArmPkg/SemihostFs: replace SetMem with ZeroMem
Date: Wed, 15 Feb 2023 15:37:32 +0100	[thread overview]
Message-ID: <20230215143732.676580-1-kraxel@redhat.com> (raw)

SetMem arguments 2+3 are in the wrong order, resulting in
the call having no effect because Length is zero.

Fix this by using ZeroMem instead.

Bugzilla: https://bugzilla.tianocore.org/show_bug.cgi?id=4205
