From f4cb410019388e450388ab001bb639b018558b71 Mon Sep 17 00:00:00 2001 From: Cao jin Date: Fri, 18 Nov 2016 19:47:38 +0800 Subject: vfio/pci: Drop unnecessary pcibios_err_to_errno() As of commit d97ffe236894 ("PCI: Fix return value from pci_user_{read,write}_config_*()") it's unnecessary to call pcibios_err_to_errno() to fixup the return value from these functions. pcibios_err_to_errno() already does simple passthrough of -errno values, therefore no functional change is expected.
