This Multi-IO card has one serial 16550-like and one parallel port connector. Here's the lspci output, after this commit is applied: 03:07.0 Serial controller: Device 4348:5053 (rev 10) (prog-if 02 [16550]) Subsystem: Device 4348:5053 Control: I/O+ Mem- BusMaster- SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx- Status: Cap- 66MHz- UDF- FastB2B- ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Interrupt: pin A routed to IRQ 21 Region 0: I/O ports at cf00 [size=8] Region 1: I/O ports at ce00 [size=8] Kernel driver in use: parport_serial Kernel modules: 8250_pci, parport_serial This commit adds an entry with the device ID to the blacklist declared in 8250_pci to prevent the driver from taking ownership. Also, and as was done for the 2S/1P variant, add a quirk to skip autodetection and set the correct type to 16550A clone. Proper entries are added to parport_serial, to support the device parallel and serial ports.
