From 56672bf52ebf7b9d6de245f7a1bf56679a39093b Mon Sep 17 00:00:00 2001 From: Alexander Graf Date: Fri, 26 Jan 2018 00:47:53 +0100 Subject: [PATCH] efi_loader: Call Exit() on return from payload in StartImage() When a UEFI payload just returns instead of calling the Exit() callback, we handle that in efi_do_enter() and call Exit on its behalf, so that the loaded_image->exit_status value is correct. We were missing that logic in StartImage(). Call it there too.
