>From 6f96e25fd4401b152adb9d91ebda0777f3532162 Mon Sep 17 00:00:00 2001 From: Yin Kangkai <kangkai.yin@xxxxxxxxx> Date: Mon, 24 Jan 2011 18:45:39 +0800 Subject: [PATCH] serial: also set the uartclk value in resume after goes to highspeed For any reason if the NS16550A was not work in high speed mode (e.g. we hold NS16550A from going to high speed mode in autoconfig_16550a()), now we are resume from suspend, we should also set the uartclk to the correct value. Otherwise it is still the old 1843200 and that will bring issues.
