[BUG] FTDI driver framing error with even parity

This is seen on widely used ftdi ft232rl chips. Setting the parity to something like 'even' results in occasional framing errors when transmitting data. Relevant timing diagrams from the logic analyzer are attached to this bug: https://bugzilla.kernel.org/show_bug.cgi?id=47921 -- Regards, Andr
