commit 824d17c57b upstream.
As has been reported the National Instruments serial cards have broken
PCI class.
The commit 7d8905d064
("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: 7d8905d064 ("serial: 8250_pci: Enable device after we check black list")
