[PATCH 2/3] x86/platform/uv: Remove spaces from OEM IDs

From: Mike Travis
Date: Thu Nov 05 2020 - 17:28:33 EST


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")
