Do you see commit 5d288dbd88606d8f215c7138b10649115d79cadd on that branch? It removes rng_seed from struct efi, hence my request to rebase your patch. IMO, best is to simply drop the 'static' from rng_seed, rename it to efi_rng_seed, and drop an extern declaration in linux/efi.h so it is accessible from your code. I'm reluctant to put it back in struct efi.
