6.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ard Biesheuvel ardb@kernel.org
commit fb318ca0a522295edd6d796fb987e99ec41f0ee5 upstream.
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.
