Browse source

[ Upstream commit 6d6887c42e ]

The xhci retaining bogus hardware states cause usb disconnect devices
connected before hibernation(s4) and refer to the commit 'f3d478858b
("usb: ohci-platform: fix usb disconnect issue after s4")' which set
flag "hibernated" as true when resume-from-hibernation and that the
drivers will reset the hardware to get rid of any existing state and
make sure resume from hibernation re-enumerates everything for xhci.
