Thanks for the patch.
I think the commit log should be rewritten (when you write it think at
someone reading it in some time - what you wrote won't probably make
any sense) but first, Bjorn are you picking this up ? It does not make
much sense to squash it in one of my pci/dwc branch commits - therefore
I am asking, just let me know.
Thanks,
Lorenzo
