Comment 65 for bug 566149

I kind of doubt it, but I'll defer to those who are more directly involved
in the patch. From what I can tell, this mostly deals with re-initializing
USB when coming back from suspend only.

Here's a copy of the commit message:

If the firmware puts a device back into D0 state at resume time, we'll

update its state in resume_noirq and thus skip the platform resume code.
Calling that code twice should be safe and we ought to avoid getting to
that point anyway, so remove the check and also allow the platform pci
code to be called for D0.

Fixes USB not being powered after resume on recent Lenovo machines.

(P.S. sorry if it's not good practice to respond to questions in this way;
I'm quite new to the system.)
