From: Matt Fleming

Hi Peter, Linus,

I've got a small patch that fixes a crash for the Google folks and their
EFI SMI driver, which was caused by dereferencing a garbage pointer.

Please consider pulling.

The following changes since commit f697036b93aa7345d4cbb3c854a76456c0ddac45:

efi: Check EFI revision in setup_efi_vars (2013-04-24 16:19:01 +0100)

efivars: only check for duplicates on the registered list (2013-04-26 16:50:01 +0100)

* Last minute bugfix for the efivars code. The google EFI SMI driver
maintains its own list of EFI variables but the efivars core was
directly accessing a different (and in this case, uninitialised) list
resulting in a crash.
