Please break your lines at 72 cols or so, and use the common subject prefix (e.g. "USB: serial: ftdi_sio: improve...") with a concise summary. > This patch improves on the baud rate generation.

Did you trace and compare the divisors actually requested by the Windows driver, or did you measure the resulting rates using a scope? Thanks, Johan
