+Subject: [PATCH] libmisc/salt.c: Use int pointer for YESCRYPT_salt_cost().
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The corresponding functions for the other hash methods all take
+a pointer to an integer value as the only paramater, so this
+particular function should do so as well.
