[ Upstream commit 145a417a39d7efbc881f52e829817376972b278c ]
RCFW_COMM_CONS_PCI_BAR_REGION is defined as BAR 2, so checking
!creq_db->reg.bar_id is incorrect and always false.
pci_resource_start() returns the BAR base address, and a value of 0
indicates that the BAR is unassigned. Update the condition to test
bar_base == 0 instead.
This ensures the driver detects and logs an error for an unassigned
RCFW communication BAR.

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.
