If USB cable is connected prior to boot, we don't get any interrupts
so we must manually check the VBUS state and report it during probe.
If we don't do it then USB controller will never know that peripheral
cable was connected till the user unplugs and replugs the cable.

Thanks. But this is a bug fix and must go in v4.7-rc
as well as stable v4.6+.
Can you please add
Cc: stable@vger.kernel.org # v4.6+

OK. I'll send the pull request for this patch.

If we should add the 'stable@verger.kernel.org',
this patch should be sent to mailing list.
So, I think that you better to send this patch including stable mailing list.
And then, I'll send pull request which apply this patch to 4.7-rc.
Thanks,
