From 2aa665ad2cb13bc79b645db41686449a47593aab Mon Sep 17 00:00:00 2001 From: Emekcan Date: Thu, 3 Nov 2022 17:43:40 +0000 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.
