By suggestion from Johan Hovold it is possible to replace ftdi_jtag_quirk with a bit more generic construction. Since all Olimex-ARM debuggers has exactly two ports, we could safely always use only second port within the debugger family.

Specifically, the device latency timer would not be updated until next

c19db4c9e49a ("USB: ftdi_sio: set device latency timeout at port
