commit 824d17c57b0abbcb9128fb3f7327fae14761914b upstream.
As has been reported the National Instruments serial cards have broken
PCI class.
The commit 7d8905d06405
("serial: 8250_pci: Enable device after we check black list")
made the PCI class check mandatory for the case when device is listed in
a quirk list.
Make PCI class test non fatal to allow broken card be enumerated.
Fixes: 7d8905d06405 ("serial: 8250_pci: Enable device after we check black list")

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
