From 10e7d0980fd40cbbdaa57349dfbabf78f7e1b5d5 Mon Sep 17 00:00:00 2001 From: Kyoungil Kim Date: Sun, 20 May 2012 17:49:31 +0900 Subject: serial: samsung: Fixed wrong comparison for baudclk_rate 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.
