Subject: [PATCH v1 1/1] ShellPkg: Fix incorrect PPTT FlagName dereference
Date: Tue, 14 Dec 2021 12:37:36 +0000	[thread overview]
Message-ID: <20211214123736.10854-1-christopher.jones@arm.com> (raw)

Bugzilla: 3770 (https://bugzilla.tianocore.org/show_bug.cgi?id=3770)

The PPTT parser in AcpiView incorrectly dereferences a pointer to
FlagName when trying to log an error with the PPTT cache flags, which
can lead to random crashes and other errors.

Also fix some spacing in the error message to ensure the message is
printed cleanly.
