From d9d959c36bec59f11c0eb6b5308729e3c4901b5e Mon Sep 17 00:00:00 2001 From: Philipp Stanner Date: Wed, 30 Oct 2024 12:27:34 +0100 Subject: PCI: Make pcim_request_all_regions() a public function MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit In order to remove the deprecated function pcim_iomap_regions_request_all(), a few drivers need an interface to request all BARs a PCI device offers. Make pcim_request_all_regions() a public interface.

It, thus, prevents getting rid of the problematic iomap table mechanism which was deprecated in commit e354bb84a4c1 ("PCI: Deprecate pcim_iomap_table(), pcim_iomap_regions_request_all()"). pcim_iounmap_region() does not have that problem. Make it public as the successor of pcim_iounmap_regions().
