From a5b45b7b952822aa5fbe842d2ee497c7c9dd7f55 Mon Sep 17 00:00:00 2001 From: Dexuan Cui Date: Tue, 23 Aug 2016 04:49:22 +0000 Subject: PCI: hv: Handle hv_pci_generic_compl() error case 'completion_status' is used in some places, e.g., hv_pci_protocol_negotiation(), so we should make sure it's initialized in error case too, though the error is unlikely here.
