-Subject: [PATCH] volume_key: Switch to libcryptsetup error callback.
+From ecef526a51c5a276681472fd6df239570c9ce518 Mon Sep 17 00:00:00 2001
+From: Miloslav Trmač <mitr@redhat.com>
+Date: Nov 07 2017 15:55:55 +0000
+Subject: Stop using crypt_get_error
-This change should be compatible with new libcryptsetup as well.
-Note that now is error set even for retry, so the code must
-clear it after successfull (but retried) password query.
+Instead of crypt_get_error, which has been removed in cryptsetup 2.0,
+set up a log callback, which is available in both older and newer
+versions.
+
+Fixes #13.
