[edk2-devel] [edk2-platforms][PATCH v1 1/1] IntelSiliconPkg: Cast UINT32 to UINT8 conversion in ReportCpuHobLib

[Michael Kubacki]

From: Michael Kubacki <michael.kubacki at microsoft.com>

REF:https://bugzilla.tianocore.org/show_bug.cgi?id=3404

Commit d3c10d3 introduced a build error in ReportCpuHobLib.c:

IntelSiliconPkg\Library\ReportCpuHobLib\ReportCpuHobLib.c(30):
  error C2220: warning treated as error - no 'object' file generated
IntelSiliconPkg\Library\ReportCpuHobLib\ReportCpuHobLib.c(30):
  warning C4244: '=': conversion from 'UINT32' to 'UINT8',
  possible loss of data

This commit explicitly cast the assignment to fix the build error.
