From a5d92ad32dad94fd8f3f61778561d532bb3a2f77 Mon Sep 17 00:00:00 2001 From: Matt Fleming Date: Mon, 17 Mar 2014 10:57:00 +0000 Subject: efivars: Stop passing a struct argument to efivar_validate() In preparation for compat support, we can't assume that user variable object is represented by a 'struct efi_variable'. Convert the validation functions to take the variable name as an argument, which is the only piece of the struct that was ever used anyway.
