Ilpo Järvinen 910ed628e5 PCI: xgene: Do PCI error check on own line & keep return value
Instead of an "if" condition with a line split, use the usual error
handling pattern with a separate variable to improve readability.

pci_generic_config_read32() already returns either PCIBIOS_SUCCESSFUL or
PCIBIOS_DEVICE_NOT_FOUND so it is enough to simply return its return value
when ret != PCIBIOS_SUCCESSFUL.

No functional changes intended.

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.
