Serge Semin e3dc79adfa PCI: dwc: Detect iATU settings after getting "addr_space" resource
Previously, dw_pcie_ep_init() did:

  dw_pcie_iatu_detect(pci);
  res = platform_get_resource_byname(pdev, IORESOURCE_MEM, "addr_space");
  if (!res)
    return -EINVAL;

The platform_get_resource_byname() can fail, and dw_pcie_iatu_detect()
doesn't depend on the "addr_space" resource, so delay it until afterwards,
i.e.,

  platform_get_resource_byname(pdev, IORESOURCE_MEM, "addr_space");
  dw_pcie_iatu_detect(pci);

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.
