From eef5ad1086403d8ac8d91208a0e8dc34734b671c Mon Sep 17 00:00:00 2001 From: Luiz Capitulino Date: Mon, 6 Aug 2012 15:49:34 -0300 Subject: [PATCH] hmp_change(): don't access DeviceEncrypted's data It's not needed. As the device name is already known, we can replace the duplicated password prompting code by monitor_read_block_device_key(). This overly simplifies hmp_change().
