From 948f5ada58b552d975d1937a3f5939414f28cacb Mon Sep 17 00:00:00 2001 From: Longfang Liu Date: Mon, 26 Sep 2022 17:33:28 +0800 Subject: 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.
