2.6.38-stable review patch. If anyone has any objections, please let us know.
------------------ From: Yin Kangkai <[email protected]> commit 95926d2db6256e08d06b753752a0d903a0580acc upstream. 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.
