Philipp Stanner	81fcf28e74	PCI: Document hybrid devres hazards ... These functions: pci_request_region() pci_request_regions() pci_request_regions_exclusive() pci_request_selected_regions() pci_request_selected_regions_exclusive() pci_intx() are "hybrid" functions that are managed if pcim_enable_device() has been called, but unmanaged otherwise. This is confusing and has already caused a bug (in 8558de401b ("drm/vboxvideo: use managed pci functions")) because users believe all PCI functions, such as pci_iomap_range(), can become managed that way, which is not the case. Add comments to the relevant functions' docstrings that warn users about this behavior.

Philipp Stanner	ae87402752	PCI: Move pci_iomap.c to drivers/pci/ ... The entirety of pci_iomap.c is guarded by an #ifdef CONFIG_PCI. It, consequently, does not belong to lib/ because it is not generic infrastructure. Move pci_iomap.c to drivers/pci/ and implement the necessary changes to Makefiles and Kconfigs. Update MAINTAINERS file. Update Documentation.
