--- Cliff Cai 2009-07-19 22:30:38

If we run vrec -w|vplay and then force system into power management course,after

resuming ,plackback will be started first,this causes the vrec -w|vplay to be

stopped.It should be a problem of oss-emulation layer.

This bug still exists after I add a 10K pull-down resistor to SCKE.

fixed now,we should deal with the scenario that,suspending to memory may happen

while the driver haven't been put into use yet,in such case,the related

registers are all reset and needed to be restored.
