Krzysztof Wilczyński 1ecbf4f3e9 PCI: cadence: Fix DMA range mapping early return error 
[ Upstream commit 1002573ee3 ]

Function cdns_pcie_host_map_dma_ranges() iterates over a PCIe host bridge
DMA ranges using the resource_list_for_each_entry() iterator, returning an
error if cdns_pcie_host_bar_config() fails.

49e427e6bd ("Merge branch 'pci/host-probe-refactor'") botched a merge so
it *always* returned after the first DMA range, even if no error occurred.

Fix the error checking so we return early only when an error occurs.

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.
