This is a check-in of the Advantech ADV950 serial driver, used with the
UNO-1150 series of industrial computers, as sourced from:
http://support.advantech.com/support/DownloadSRDetail_New.aspx?SR_ID=1-GLBRCD&Doc_Source=Download
This builds with kernel 3.0.1, but does not build with contemporary
kernels (i.e. ones that are still in support).
I suspect this is a hacked up version of Russel King's 8250 serial
driver from 2001. First step, let's get it building against the current
kernel (v4.10.1) and then we'll look at integrating this into 8250
proper.
