Comment(by andy):
I have added your second patch on stable, and put both on stable-tracking
now. Thanks again for the work on it.
It's pretty interesting actually, this new sticky LCM behaviour of "jazzy
lines" is provoked solely by taking down LDO6, the LCM power during
suspend. If I have LDO6 kept up during suspend, no jazzy lines.
However while we don't take down LDO6 and we didn't enter deep sleep in
LCM ASIC, I guess we are burning a little power in suspend we don't need
to... it's less of an issue than WSOD :-) but it still needs looking at.
