From 2800a911ced1540baa78de7494218aaf1c7dc4fa Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Krzysztof=20Wilczy=C5=84ski?= Date: Fri, 8 May 2026 04:35:42 +0000 Subject: PCI/sysfs: Remove pci_create_legacy_files() and pci_sysfs_init() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Currently, pci_create_legacy_files() and pci_remove_legacy_files() are no-op stubs. With legacy attributes now handled by static groups registered via pcibus_groups[], no call site needs them. Remove both functions, their declarations, and the call sites in pci_register_host_bridge(), pci_alloc_child_bus(), and pci_remove_bus(). Remove the pci_sysfs_init() late_initcall and sysfs_initialized. The late_initcall originally existed to create all the dynamic PCI sysfs files, but with both resource and legacy attributes now handled by static groups, it is no longer needed. Remove the legacy_io and legacy_mem fields from struct pci_bus which were used to track the dynamically allocated legacy attributes.
