Subject: serial/imx.c : wrong baudrate at resume if console is on UART

Hi,
while testing suspend/resume on i.MX27, I meet a problem on resume : if
the console is on the UART the baudrate it not restored properly (I get
random bitrate between 50 to 2Mbps). Here is a patch to add pm to the
uart_ops (but the problem occurs also without this patch) :

What is strange is that giving wrong structures (platform_device instead
of device) in suspend/resume functions as in following patch "fix" the
problem :

Do you have any idea of what could be wrong there ?
Many thanks,
Eric
