Subject: [PATCH 2/3] x86/platform/uv: Remove spaces from OEM IDs
Date: Thu, 5 Nov 2020 16:27:40 -0600
Message-ID: <20201105222741.157029-3-mike.travis@hpe.com> (raw)
In-Reply-To: <20201105222741.157029-1-mike.travis@hpe.com>
Testing shows that trailing spaces caused problems with the OEM_ID and
the OEM_TABLE_ID. One being that the OEM_ID would not string compare
correctly. Another the OEM_ID and OEM_TABLE_ID would be concatenated
in the printout. Remove any trailing spaces.
Fixes: 1e61f5a95f191 ("Add and decode Arch Type in UVsystab")
