From: Vitaliy Tomin <tomin@xxxxxxxxxxx> commit d2b00516de0e1d696724247098f6733a6ea53908 upstream. Add support for Advantech PCI-1611U card Advantech provides opensource drivers for this and many others card based on legacy copy of 8250_pci driver called adv950 https://www.advantech.com/emt/support/details/driver?id=1-TDOIMJ It is hard to maintain to run as out of tree module on newer kernels. Just adding PCI ID to kernel 8250_pci works perfect.
