The introduction of pci_register_host_bridge() kernel interface allows PCI host controller drivers to create the struct pci_host_bridge object, initialize it and register it with the kernel so that its corresponding PCI bus can be scanned and its devices probed. The host bridge device release function pci_release_host_bridge_dev() is a static function common for all struct pci_host_bridge allocated objects, so in its current form cannot be used by PCI host bridge controllers drivers to initialize the allocated struct pci_host_bridge, which leaves struct pci_host_bridge devices release function uninitialized. Since pci_release_host_bridge_dev() is a function common to all PCI host bridge objects, initialize it in pci_alloc_host_bridge() (ie common host bridge allocation interface) so that all struct pci_host_bridge objects have their release function initialized by default at allocation time, removing the need for exporting the common pci_release_host_bridge_dev() function to other compilation units.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
