Merge tag 'efi-urgent-for-v5.10-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull EFI fixes from Borislav Petkov:
"More EFI fixes forwarded from Ard Biesheuvel:
- revert efivarfs kmemleak fix again - it was a false positive
- make CONFIG_EFI_EARLYCON depend on CONFIG_EFI explicitly so it does
not pull in other dependencies unnecessarily if CONFIG_EFI is not
set
- defer attempts to load SSDT overrides from EFI vars until after the
efivar layer is up"
* tag 'efi-urgent-for-v5.10-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
efi: EFI_EARLYCON should depend on EFI
efivarfs: revert "fix memory leak in efivarfs_create()"
efi/efivars: Set generic ops before loading SSDT
