Hi Tony,
Please ignore Sergei's nit-picky comments about extra parenthesis. I'm
fine with extra parens if they add to readability, either for me or for
the patch submitter. It's not like parens are a precisions resource.
Sergei, please stop sending non-constructive feedback on xHCI driver
patches. It adds unnecessary patch churn.
In this case, since this patch will be backported to stable and distro
kernels, we really don't want the patch to touch any code it doesn't
have to. A bug fix patch should just address the bug, and all cosmetic
changes should be in a separate patch.
Tony, if you still want to change the lines in xhci_stop and
xhci_suspend to remove the extra parens, please add that to the cleanup
patch you submitted and re-send the patch.
