From d6566113102e852937d0845a528337484ae85f95 Mon Sep 17 00:00:00 2001 From: Masahisa Kojima Date: Sun, 20 Nov 2022 09:21:16 +0900 Subject: [PATCH] eficonfig: expose eficonfig_create_device_path() Following commits are adding support for UEFI variable management via the eficonfig menu. Those functions needs to use eficonfig_create_device_path() to construct the full device path from device path of the volume and file path, so move it out of their static declarations.
