Date: Thu, 22 Sep 2022 16:39:24 +0800 From: Longfang Liu <liulongfang@...wei.com> To: <alex.williamson@...hat.com>, <jgg@...dia.com>, <shameerali.kolothum.thodi@...wei.com> CC: <cohuck@...hat.com>, <linux-kernel@...r.kernel.org>, <linuxarm@...neuler.org>, <liulongfang@...wei.com> Subject: [PATCH v2 1/5] hisi_acc_vfio_pci: Fixes error return code issue During the process of compatibility and matching of live migration device information, if the isolation status of the two devices is inconsistent, the live migration needs to be exited. The current driver does not return the error code correctly and needs to be fixed.
