From 44e985938e85503d0a69ec538e15fd33c1a4df05 Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Mon, 7 Nov 2022 15:31:08 -0600 Subject: [PATCH] Revert "PCI: Clear PCI_STATUS when setting up device" This reverts commit 6cd514e58f12b211d638dbf6f791fa18d854f09c. Christophe Fergeau reported that 6cd514e58f12 ("PCI: Clear PCI_STATUS when setting up device") causes boot failures when trying to start linux guests with Apple's virtualization framework (for example using https://developer.apple.com/documentation/virtualization/running_linux_in_a_virtual_machine?language=objc) 6cd514e58f12 only solved a cosmetic problem, so revert it to fix the boot failures.
