From c4471e3408d85c51a69991974985fe283d869eac Mon Sep 17 00:00:00 2001 From: Michael Brown Date: Tue, 5 Mar 2024 20:00:15 +0000 Subject: [efi] Add efi_path_guid() utility function EFI provides no API for determining the partition GUID (if any) for a specified device handle. The partition GUID appears to be exposed only as part of the device path. Add efi_path_guid() to extract the partition GUID (if any) from a device path.
