Two functions allocate a host bridge: devm_pci_alloc_host_bridge() and
pci_alloc_host_bridge(). At the moment, only the unmanaged one initializes
the PCIe feature bits, which prevents from using features such as hotplug
or AER on some systems, when booting with device tree. Make the
initialization code common.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
