From 755d42d4209eda07836b256730e8686c37b18939 Mon Sep 17 00:00:00 2001 From: Heinrich Schuchardt Date: Sat, 1 Jun 2019 19:29:39 +0200 Subject: [PATCH] efi_loader: correct HandleProtocol() The UEFI specification requires that when a protocol is opened via HandleProtocol() the agent handle is the image handle of the EFI firmware (see chapter on EFI_BOOT_SERVICES.OpenProtocol()). Let efi_handle_protocol() pass efi_root as agent handle to efi_open_protocol().
