Subject: [PATCH] qemuDomainSecretAESSetup: Allocate and return 'secinfo' here
|
|

Rather than passing in an empty qemuDomainSecretInfoPtr allocate it
|
|
in this function and return it. This is done by absorbing the check from
|
|
qemuDomainSecretInfoNew and removing the internals of
|
|
qemuDomainSecretInfoNew.
