From 9d38ffc5d82839cdc9effb2e9ee84a6941a25e1a Mon Sep 17 00:00:00 2001 From: Eric Auger Date: Mon, 2 May 2022 02:42:21 -0700 Subject: [PATCH] hw/vfio/pci: fix vfio_pci_hot_reset_result trace point "%m" format specifier is not interpreted by the trace infrastructure and thus "%m" is output instead of the actual errno string. Fix it by outputting strerror(errno).
