From 844177a80753fc173131f3e591124c8dcbc89812 Mon Sep 17 00:00:00 2001 From: Heiner Kallweit Date: Sat, 23 Mar 2024 18:16:36 +0100 Subject: [PATCH] PCI: Remove unused pci_enable_device_io() After the last user was removed, remove this PCI core function. It's very unlikely that we'll see a new device requiring io space access, even though memory space access is supported.
