-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.
