Subject: [S390] return 'count' for successful execution of dasd_eer_enable.
From: Horst Hummel <horst.hummel@...ibm.com>
[S390] return 'count' for successful execution of dasd_eer_enable.
Currently the return value of 'dasd_eer_enable' is returned - even if the
function returned '0'. Now return 'count' for successful execution.
