In that process, it appears TIOCSERCONFIG ioctl does not respect the UPF_FIXED_TYPE flag. uart_do_autoconfig gets called which passes UART_CONFIG_TYPE flag to config_port call. > > The same problem seems be to reported some time back to the maintainers which can be found in the link - https://www.spinics.net/lists/linux-serial/msg29169.html. But the patch didn't make it through to the mainline kernel. Could you please let us know the resolution of that thread? Is it rejected/accepted? That patch was from 2018, I can't remember what I reviewed last week :) If it's not in the kernel tree today, then no, it was not accepted. If you need something like this, please test that patch and resend it with your signed-off-by and we will be glad to review it. thanks, greg k-h
