Subject: [PATCH v2] serial: set correct baud_base for Oxford Semiconductor
 Ltd EXSYS EX-41092 Dual 16950 Serial adapter

The PCI-card identified as "Oxford Semiconductor Ltd EXSYS EX-41092 Dual
16950 Serial adapter" is only usable with other devices (i.e. not the same
card) after doing a "setserial /dev/ttyS<n> baud_base 115200".  This
baud_base should be default for this card.
