Re: [PATCH] serial: 8250_dw: Do not reclock if already at correct rate

When userspace opens the console, we call set_termios() passing a termios with the console's configured baud rate. Currently this causes dw8250_set_termios() to disable and then re-enable the UART clock at the same frequency as it was originally. This can cause corruption of any concurrent console output. Fix it by skipping the reclocking if we are already at the correct rate.

Again, why the link? What does that help with? Our tools add a Link: tag to this public email thread, not a google gerrit instance.
