[PATCH 07/10] efi: Use typed function pointers for runtime services table

From: Ard Biesheuvel
Date: Tue Jan 31 2017 - 08:26:38 EST


Instead of using void pointers, and casting them to correctly typed
function pointers upon use, declare the runtime services pointers
as function pointers using their respective prototypes, for which
typedefs are already available.
