From 4a6afd60733c75369680f4a40c82b7c8528f4a7a Mon Sep 17 00:00:00 2001 From: Philipp Stanner Date: Wed, 16 Oct 2024 11:49:04 +0200 Subject: PCI: Make pcim_iounmap_region() a public function The function pcim_iounmap_regions() is problematic because it uses a bitmask mechanism to release / iounmap multiple BARs at once. 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().
