[Qemu-devel] [PATCH 3/7] HACK: HobLib: workaround infinite loop

[marcandre . lureau]

From: Marc-André Lureau <address@hidden>

Without this hack, GetNextHob() loops infinitely with the next patch.
I don't understand the reason.

The loop is triggered by the GetFirstGuidHob (&gTpmErrorHobGuid) call.
