Merge tag 'efi-fixes-for-v6.1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/efi/efi

Browse Source 
Pull EFI fixes from Ard Biesheuvel:

 - A pair of tweaks to the EFI random seed code so that externally
   provided version of this config table are handled more robustly

 - Another fix for the v6.0 EFI variable refactor that turned out to
   break Apple machines which don't provide QueryVariableInfo()

 - Add some guard rails to the EFI runtime service call wrapper so we
   can recover from synchronous exceptions caused by firmware
