port->baudclk_rate should be compared to the rate of port->baudclk, because port->baudclk_rate was assigned as the rate of port->baudclk previously. So to check that the current baudclk rate is same as previous rate, the target of comparison sholud be the rate of port->baudclk.

(Cc'ed Greg) Acked-by: Kukjin Kim <redacted> Greg, this is needed to fix the wrong comparison for baudclk_rate for Samsung Serial. Could you please pick this up in your fix tree? Thanks.
