Pretty much every driver that tries this eventually ends up with
a blacklist of devices that don't implement MSI correctly.
Did you test this with all the models that are supported by this driver?

I don't have all models supported by this driver. So I could only test with 
this one:
#lspci -v -s 02:0a.1
02:0a.1 Serial controller: Intel Corporation Device 8811 (prog-if 02 [16550])
        Subsystem: Intel Corporation Device 8811
        Flags: bus master, fast devsel, latency 0, IRQ 40
        I/O ports at 9040 [size=8]
        Memory at 9fefb2f0 (32-bit, non-prefetchable) [size=16]
        Capabilities: [40] MSI: Mask- 64bit- Count=1/1 Enable+
        Capabilities: [50] Power Management version 2
        Kernel driver in use: pch_uart

There are 3 more for the other ports.
