This function should take a pointer, not an address. Update it along with all users.
Signed-off-by: Simon Glass sjg@chromium.org ---
Changes in v5: - Drop the enum / mem_type patch as it is not needed - Drop the patch to remove extra brackets in efi_mem_carve_out()
Changes in v3: - Add comment to struct efi_device_path_memory - Use a pointer for the values in struct efi_device_path_memory
Changes in v2: - Drop patch 'Convert efi_get_memory_map() to return pointers' - Drop patch 'efi_loader: Make more use of ulong' - Significantly expand and redirect the series
