    usb, xhci: Clear warm reset change event during init · 79c3dd81
    Don Zickus authored
    I noticed on my Panther Point system that I wasn't getting hotplug events
    for my usb3.0 disk on a usb3 port.  I tracked it down to the fact that the
    system had the warm reset change bit still set.  This seemed to block future
    events from being received, including a hotplug event.
    
    Clearing this bit during initialization allowed the hotplug event to be
    received and the disk to be recognized correctly.
    
    This patch should be backported to kernels as old as 2.6.39.
