serial: serial_cs: oxsemi quirk breaks resume
Quirk is applied on all cards with given manfid (is it that correct?). Unfortunately, that quirk breaks resume on zaurus with billionton bluetooth card inserted: c950ctrl is 0 and outb() faults. I believe it is simply not a multiport card. (info->multi == 1). ... ... confirmed by printks.
