Sorry about that. I wrongly assumed that PNP to be unique to our platform :S. As an initial workaround we could change the Kconfig to && !SERIAL_8250_PNP depends on SERIAL_8250 && PNP && !SERIAL_8250_PNP That way the driver can still be used with the proper kernel configuration (which is fine in an embedded environment) The second step could be to call the fintek probe from the 8250_pnp.... what dow you think about this?
