Subject: [PATCH v2 1/8] SecurityPkg: also clear
HashInterfaceHob.SupportedHashMask
From: Marc-André Lureau <marcandre.lur...@redhat.com>
Commit 4cc2b63bd829426b05bad0d8952f1855a10d6ed7 fixed an out of bounds
ZeroMem() call. However, as Laszlo Ersek pointed out, the intent was to clear
all but the Identifier (to revert the effect of RegisterHashInterfaceLib()).
For that, it should clear the SupportedHashMask too.
