Subject: [PATCH] qemuDomainSecretAESSetupFromSecret: Use 'qemuAliasForSecret'
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replace qemuDomainGetSecretAESAlias by the new function so that we can
reuse qemuDomainSecretAESSetupFromSecret also for setting up other kinds
of objects.
