From 2aa665ad2cb13bc79b645db41686449a47593aab Mon Sep 17 00:00:00 2001

Subject: [PATCH] smm_gateway: GetNextVariableName Fix
GetNextVariableName() should return EFI_BUFFER_TOO_SMALL
when NameSize is smaller than the actual NameSize. It
currently returns EFI_BUFFER_OUT_OF_RESOURCES due to setting
max_name_len incorrectly. This fixes max_name_len error by
replacing it with actual NameSize request by u-boot.
