+Subject: [PATCH] loader/efi/chainloader: Simplify the loader state
+
+The chainloader command retains the source buffer and device path passed
+to LoadImage(), requiring the unload hook passed to grub_loader_set() to
+free them. It isn't required to retain this state though - they aren't
+required by StartImage() or anything else in the boot hook, so clean them
+up before grub_cmd_chainloader() finishes.
