s390x/css: Allocate channel_subsys statically
There's no need to use g_malloc0() to allocate the channel_subsys struct, just use a static variable. Cc: Cornelia Huck <cornelia.huck@de.ibm.com> Cc: Christian Borntraeger <borntraeger@de.ibm.com> Cc: Richard Henderson <rth@twiddle.net> Cc: Alexander Graf <agraf@suse.de> Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Message-Id: <1455656347-29033-3-git-send-email-ehabkost@redhat.com> Reviewed-by: Cornelia Huck <cornelia.huck@de.ibm.com> [adapted on top of indicator changes] Signed-off-by: Cornelia Huck <cornelia.huck@de.ibm.com>
