Pull EFI updates from Ard Biesheuvel:
 "Not a lot happening in EFI land this cycle.

   - Prevent kexec from crashing on a corrupted TPM log by using a
     memory type that is reserved by default

   - Log correctable errors reported via CPER

   - A couple of cosmetic fixes"

* tag 'efi-next-for-v6.12' of git://git.kernel.org/pub/scm/linux/kernel/git/efi/efi:
  efi: Remove redundant null pointer checks in efi_debugfs_init()
  efistub/tpm: Use ACPI reclaim memory for event log to avoid corruption
  efi/cper: Print correctable AER information
  efi: Remove unused declaration efi_initialize_iomem_resources()
