Subject: [PATCH 0/3] efi: stmm: Fix for incorrect buffer allocation and cleanups

One critical fix for the EFI StMM driver and two smaller cleanups.

I'm carefully optimistic that we will get better test coverage in the
future: I have a working RPMB model for QEMU, and this is where the
crash was found now and debugged in.
