From fb318ca0a522295edd6d796fb987e99ec41f0ee5 Mon Sep 17 00:00:00 2001 From: Ard Biesheuvel Date: Thu, 4 Jul 2024 10:59:23 +0200 Subject: [PATCH] x86/efistub: Avoid returning EFI_SUCCESS on error The fail label is only used in a situation where the previous EFI API call succeeded, and so status will be set to EFI_SUCCESS. Fix this, by dropping the goto entirely, and call efi_exit() with the correct error code.
