From: Philipp Stanner Date: Wed, 30 Oct 2024 11:27:43 +0000 (+0100) Subject: PCI: Remove pcim_iomap_regions_request_all() X-Git-Tag: v6.13-rc1~66^2~28^2~5 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=6d9c59212523e719a63575222f1cd1b0aca3da4f;p=thirdparty%2Fkernel%2Flinux.git PCI: Remove pcim_iomap_regions_request_all() pcim_iomap_regions_request_all() have been deprecated in commit e354bb84a4c1 ("PCI: Deprecate pcim_iomap_table(), pcim_iomap_regions_request_all()"). All users of this function have been ported to other interfaces by now. Remove pcim_iomap_regions_request_all().
