From e07368ea57d224557570a6715dcffdbc883a8079 Mon Sep 17 00:00:00 2001 From: Heinrich Schuchardt Date: Wed, 19 Jul 2023 06:43:08 +0200 Subject: efi_loader: support all uclasses in device path On devices with multiple USB mass storage devices errors like Path /../USB(0x0,0x0)/USB(0x1,0x0)/Ctrl(0x0) already installed. are seen. This is due to creating non-unique device paths. To uniquely identify devices we must provide path nodes for all devices on the path from the root device. Add support for generating device path nodes for all uclasses.
