From 68a30e9bf0e494057a889e06623dd0d8ab95acf7 Mon Sep 17 00:00:00 2001

Subject: [PATCH 1/6] print_mechanism() ignored bad returncodes from the
 called function token_specific_get_mechanism_list(). So
 the token init was just running fine but mechanism list
 kept empty (eg. because of wrong adapter
 configuration). Fixed this and adjusted some of the
 related log messages.
