Note I just realized this will not apply cleanly, I've 3 patches in my
local tree adding power_save quirks and I'm still waiting for feedback
on the 2 others. I did not realize this one depended on the others.

I will send out the entire series when I've test results on the
other 2 models.

Regards,

Hans
