Merge tag 'efi-fixes-for-v5.7-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/efi/efi into efi/urgentefi-urgent-2020-05-24
Pull EFI fixes from Ard Biesheuvel:
"- fix EFI framebuffer earlycon for wide fonts
- avoid filling screen_info with garbage if the EFI framebuffer is not
available
- fix a potential host tool build error due to a symbol clash on x86
- work around a EFI firmware bug regarding the binary format of the TPM
final events table
- fix a missing memory free by reworking the E820 table sizing routine to
not do the allocation in the first place
- add CPER parsing for firmware errors"
