Subject: [PATCH 2/2] s390/pci: handle function enumeration after sriov enablement
Date: Thu, 13 Sep 2018 14:41:24 +0200 [thread overview]
Message-ID: <20180913124124.14632-3-sebott@linux.ibm.com> (raw)
In-Reply-To: <20180913124124.14632-1-sebott@linux.ibm.com>
Implement add_vfs|del_vfs callbacks as empty functions. VF
creation will be triggered by the hotplug code.
