Yes, please rebase your work on top of that branch. I'll merge it to my
usb-next branch before applying your patch.

No, if you rebase your work on top of the above branch, you won't have
to deal with cp210x_get_termios() which has now been removed.

Just add support for software flow control to the new
cp210x_set_flow_control() function (and cp210x_termios_change()).

I think you can even drop get_special_chars() and just leave the rest
set as NUL, which appears to be the default.
