    Subject[PATCH 3.14 36/37] serial: 8250_pci: Add support for 12 port Exar boards
    Date
    3.14-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Soeren Grunewald <soeren.grunewald@desy.de>

    commit be32c0cf0462c36f482b5ddcff1d8371be1e183c upstream.

    The Exar XR17V358 can also be combined with a XR17V354 chip to act as a
    single 12 port chip. This works the same way as the combining two XR17V358
    chips. But the reported device id then is 0x4358.
