Passing fewer arguments is better and mem_iv_size is never used. Let's keep only one argument and make it cleaner.

Signed-off-by: Hatim Ali hatim.rv@samsung.com Signed-off-by: Akshay Saraswat akshay.s@samsung.com Acked-by: Simon Glass sjg@chromium.org --- Changes since v1: - Added "Acked-by". - Removing only "mem_iv_size" argument now.
